How to generate multiple payment files from a batch payment/payment process request?

Summary:

We've a requirement to generate a separate payment number for each invoice and the payment file which is sent to the bank should contain only one payment related information. We've explored the 'Pay Each Invoice Alone' at Supplier Site level, we are able to generate separate payments for each invoice. But we're not sure how to generate a separate payment file for each payment.

When a batch payment is made, only one payment file is generated with all payments made in it. Is it possible to have multiple payment files to be equal to the number of payments made? For example, we've paid 10 invoices from one payment process request template. Is it possible to have a payment file for each once a batch payment is made?
