How to send customise Notification when Invoice is Rejected using AME

we are trying to implement  AME for Invoice Approval Process in R12.1.3.

Business Process requires to Reject Invoice based on certain Conditions and send Notification to The Keyer with the message due to which condition the Invoice is being Rejected.

There are several situations we have to reject the Invoice.

I have used Production Rule to Reject the Invoice Automatically when certain conditions apply.

Standard AME does not send any notification for Automatic Rejection.

if there are 5 Rules each will reject the Invoice based on the Conditions defined in them.

Question: is it possible to customise the Workflow to send Rejection Notification with the information due to which condition the Invoice is being rejected?
