How to set Payee Bank Account at entered AP invoice?

Oracle Cloud R13 (update 23B) 

There is a requirement razed by a Customer to set Payment Bank Account on AP Invoices.

Meaning, once an invoice is entered and saved, we need to know from which Bank Account it will be paid.

The reason is Cash Forecasting. The Customer needs to know exactly how much is to be paid from each Bank Account at every point of time.

Thanks in Advance,
