adding "ungroup sheets" to existing vbs code

Found this code for converting XLSX to XLSM which works great on a different project. With this project when I open the excel file I need to "ungroup sheets" in the workbook then save_as xlsm. There are about 6 tabs total if that matters.

I execute it in the same directory as the excel file via a batch file:
start /min /wait "c:\Batch_Automation\xlsxtoxlsm.vbs" "C:\Batch_Automation\CCYY_MM_RUN_MMDDCCYY.xlsx" "C:\Batch_Automation\CCYY_MM_RUN_MMDDCCYY.xlsm"


Question: How do you add ungroup sheets to this code?
File name: XlsxToXlsm.vbs

------
if WScript.Arguments.Count < 2 Then
    WScript.Echo "Error! Please specify the source path and the destination. Usage: XlsxToxlsm SourcePath.xlsx Destination.xlsm"
    Wscript.Quit
End If
Dim oExcel
Set oExcel = CreateObject("Excel.Application")
Dim oBook
Set oBook = oExcel.Workbooks.Open(Wscript.Arguments.Item(0))
oBook.Worksheets(1).Activate
oBook.Worksheets(2).Activate
oBook.Worksheets(3).Activate
oBook.Worksheets(4).Activate
oBook.Worksheets(5).Activate
oBook.Worksheets(6).Activate


oBook.SaveAs WScript.Arguments.Item(1), 52
oBook.Close False
oExcel.Quit

Thank you,
