T&E Can expense report sheet_name be modified during approval process

We are PeopleSoft 9.2 thru PUM41.

Is there a way to set up the APPROVAL PRIVILEGE TEMPLATE (or someplace else) to allow an approver to update the "SHEET_NAME" field on an expense report?

The only place I see that allows that type of change is by doing the MODIFY APPROVED TRANSACTIONS. (navigation Financials/Supply Chain - Travel and Expenses - Approve Transactions - Modify Approved Transactions

I would like to allow the PREPAY AUDITOR level of approver the option to update that field during the regular approval process. Is this possible?

Thanks!!

Mike
