You say "New Worksheet". Are you inserting the worksheet via
Insert>Worksheet?
If so, perhaps you could set up a sheet template with the drop-downs already
entered.
Open a new workbook.
Delete all but one sheet.
Enter a list of customer names in any column, say P1
100(or as many customers
as you forsee). Name this range as MyList.
You could hide that column if you don't want to see it. Or you could enter it
on any sheet in your original workbook so you don't have to duplicate it.
Select a range of cells then Data>Validation>Allow>List.
Enter =MyList
Check "in cell dropdown" and "ignore blanks".
Save the workbook as Save As>File Type>Template(*.xlt)
Name it SHEET, Excel will add the .XLT
Save it to your XLSTART folder.
This now becomes the default worksheet when you Insert>Worksheet.
Click on any cell in your Validated range and an arrow will appear. Click
arrow to get your list to choose from.
