Powershell to Copy a User, but fill in details from CSV

Hi,

I want to create a Powershell Script that creates New Users from a CSV file. This I have done.
However, I want to be able to copy the Group Memberships from another User to these New Users. Preferably, a column in the CSV to detail which User to copy from, since we have a number of Template Users with various permissions.

I have the following two scripts that - when run - kind of do what I want. The first Script pulls the details from the CSV file:-

#Import the PowerShell module containing AD CMDLETS
Import-Module ActiveDirectory

#Read a CSV File with the User or Group details and create an account in AD for each entry
Function Create-ADAccountsFromCSV {
    Param (
        [parameter(Mandatory=$true)][string]$CSVPath,
        [parameter(Mandatory=$true)][string]$Type,
        [parameter(Mandatory=$true)][string]$OrgUnit
        )
    if (($Type -ne "Group") -and ($Type -ne "User"))
    {
        Throw New-Object System.ArgumentException("Type parameter must be specified as either 'User' or 'Group'.")
    }

    #Read the CSV File
    $csvData = Import-Csv $CSVPath
    foreach ($line in $csvData) {
 #Create a hash table of the account details
        $accountTable = @{
            'givenName'=$line.FirstName
            'sn'= $line.LastName
            'displayName'= $line.DisplayName
            'sAMAccountName'= $line.sAMAccountName
            'password' = $line.Password
            'description' = $line.Description
            'office' = $line.Office
            'officephone' = $line.Phone
            'emailaddress' = $line.Email
            'streetaddress' = $line.Address1
            'pobox' = $line.Address2
            'city' = $line.City
            'state' = $line.County
            'postalcode' = $line.Postcode
            'department' = $line.Department
            'company' = $line.Company
            'group1' = $line.Group1
            'group2' = $line.Group2


            'ou' = $OrgUnit  

        }
        if ($Type -eq "User")
        {
            #Call the function to create a User Account
            CreateUser -AccountInfo $accountTable
        }
        if ($Type -eq "Group")
        {
            #Call the function to create a Group Account
            CreateGroup -AccountInfo $accountTable
            
            #Get New Group
            $groupFilterString = "samAccountName -like `"" + $line.sAMAccountName + "`""
            $group = Get-ADGroup -Filter $groupFilterString
            #Walk through each member column associated with this group
            $memberColumnNumber = 1
            $memberColumn = "Member" + $memberColumnNumber
            #While a member column still exists, ad the value to a Group

This code actually creates the Users and puts them in the OU:-

#NOTE: YOU MUST RUN "PREPARE TO CREATE USERS AND GROUPS FROM CSV.PS1" BEFORE YOU RUN THIS SCRIPT
#IF YOU GET THE ERROR:
    #Create-ADAccountsFromCSV : The term 'Create-ADAccountsFromCSV' is not recognized as the name of 
    #a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path
    # was included, verify that the path is correct and try again.
#THEN YOU'VE NOT RUN THAT COMMAND FIRST!!!!!

#Create Users from the CSV File in C:\CSVs\NewUsers.csv - you need to edit the OrgUnit entry.
#EXAMPLE:
#Create-ADAccountsFromCSV -CSVPath "C:\CSVs\NewUsers.csv" -OrgUnit "OU=Staff,OU=Users,OU=Waterloo Lodge,OU=Education,DC=ACE,DC=Local" -Type "User"

Create-ADAccountsFromCSV -CSVPath "C:\CSVs\NewUsers.csv" -OrgUnit "OU=Users,OU=OFFICE,OU=OU,DC=DOMAIN,DC=Local" -Type "User"

Select all Open in new window

However, if you run these one after the other, you get asked for the new User Name, which is fine(ish) but it requires you putting the names in one by one. It also asks who the Groups should be copied from - which I can probably live with!

is it possible to do this all in one go? For the script to go through the CSV file and create the New User(s) copying the Group Memberships from another User - preferably also specified in the CSV (which will obviously need updating!)? Could it even be done to copy the OU from the existing User to the New one?

I've attached a basic CSV file, too!
