How to stop Payment Request while another one is in Process

Dear Team

in R12, is there any way to stop Payment Request at initial stage if another Payment Request is in Process. To explain the question, below are the steps

1. We created a Payment request for specific Bank account and this batch remains IN PROCESS

2. We created another Payment request with same bank/PPP

3. Second batch allows to select the Invoices, but "Build Program" fails. The output shows the earlier payment request details (i.e. Step 1 Payment request which is still not confirmed)

Now, is there any way that we can stop processing of Payment request 2 as soon as user selects the same parameters (PPP, Bank account etc)
