I'm not sure if Receipt Stacks is the best solution to this problem. Receipt Stacks are meant to allow duplicate receipt numbers for different depts. See KB # BB96904. You could, I suppose, set up a receipt stack to use only for editing receipts.

In our office, we issue hundreds of receipts per day, and in the midst of legit receipts being created by data entry personnel, I could be updating a receipt letter and using up a receipt number. I keep track of these receipt numbers by always using the same "fake" constituent - Mr. Edit R. Letter - to edit receipts. That way, all the "false" receipt numbers are under his record. Our auditors are fine with this process, but you might want to check with your finance dept.
