If we have a group of invoices that are listed under a PO # and that PO is out of funds and a new PO # is created, we have to go into each invoice individually to change the PO # that the invoice is associated with. Or if a group of invoices come in without a PO # and fall into the Expense invoice section, we have to individually invalidate and edit to include the PO #. We would like the ability to do this for the entire group.
