Hi Atul,
This seems to be regular requirement, but this is not possible with standard behavior because almost all banks use the same standard format.
how ever you can achieve this by doing below by taking ABAPer Help.
Copy RFFO* program and create Z RFFO program
Ask him to modify the FM and assign the ZRFF program in FBZP.
I can say contact your Abaper to Achieve this be doing some modification.
Regards,
Sree
