Create a fake bank to complete invoice match process to clear expense accrual ISSUE?

When we create a purchase order and make payment on an expense credit card we run into an issue because the information remains on the accrual showing that we are still liable for this expense when in fact we are not.

AP never receives an invoice to complete the match process which is the trigger to remove the PO from the accrual.

Since the invoice has already been paid on an expense credit card we don’t want to issue another payment but need a way for AP to complete the match to clear the accrual.

Can we set up a fake bank in order to process these invoices paid on a credit card and not have any payments made?
