Stop processing over billing invoice

Summary:

When AP overbills an invoice, they are getting warning message & still able to override it & create invoice. We want to stop the invoice creation process at this stage& AP should not able to create invoice. Is that possible to do it?

Reason being: When we match po invoice, its going on two holds - Amount Ordered , Amount received. PO requester unaware of the overbill hold, receive the po & chase AP for payment. We want AP not to process it at all.
