Send confirm receipt notification when prepayment invoice matched to PO goes on hold

Summary:

Prepayment Invoice goes on hold when matched to PO having match option as 'Order' and match approval level as '3-way'. In this case, confirm receipt notification is not sent to the requester.

However, if standard Invoice goes on hold when matched to PO having match option as 'Order' and match approval level as '3-way', confirm receipt notification gets sent to the requester.

Is there a way wherein we can edit the BPM worklist task 'ConfirmReceiptRequestForAction' to send the notification to the requester when Prepayment Invoice goes on hold when matched to PO? If yes, how to achieve it?
