Not especially difficult, but if you want to use a macro to do this, then would it work to have the macro determine next week's date and insert it, rather than inserting a formula to calculate it? I assume that once a sheet is created and set up for next week's date, it will always have the same date.
The macro would look something like this:
This code creates a sheet called Template (change as necessary) to be the last sheet in the workbook, then inserts a date one week from today in cell A1 of the new sheet.
