How to add a parameter to this custom function for the number of columns?

I had this question after viewing How to write a custom Excel 2016 function that gets first two characters of cell if numbers?.

The current custom function works with 3 columns.  I would like to be able to use a different number in other situations.

The current solution uses a Range(), so can already handle any number of columns.

In the function 3 is hard-coded, but I would like it to be passed to the function.

Function CombineText(rg As Range) As String
    Dim col As Integer
    If rg.Columns.Count = 3 And rg.Rows.Count = 1 Then
        For col = 1 To 3
            If rg.Cells(1, col) = "" Then
                CombineText = CombineText & "00"
            Else
                CombineText = CombineText & Left(rg.Cells(1, col), 2)
            End If
            If col < 3 Then
                CombineText = CombineText & "-"
            End If
        Next col
    End If
End Function

Sorry, didn't study prior solution, try these adjustments please.

Function CombineText(rg As Range) As String
    Dim col As Integer
    If rg.Rows.Count = 1 Then
        For col = 1 To rg.Columns.Count
            If rg.Cells(1, col) = "" Then
                CombineText = CombineText & "00"
            Else
                CombineText = CombineText & Left(rg.Cells(1, col), 2)
            End If
            If col < rg.Columns.Count Then
                CombineText = CombineText & "-"
            End If
        Next col
    End If
End Function

Great use of count rather than having to enter the number of columns. Thanks
