FQ events to change Payment file name for Payment Medium

Hi,

I have observed that we can give only static payment file name along with file path in the variant for Payment Medium program (SAPFKPY3). When Payment file is generated, post payment run (FPY1), the static payment file name is appended with a 3 digit counter,like FILE001, FILE002 etc. and saved into the file path.

Whether there is any FQ event where we can write a logic to have dynamic file name or  dynamic parts to be appended with the static file name. Also how to stop the counter being appended with the file name.

Thanks & Regards,
