Is there anyway to change the payment process request standard reports to order by paygroup?

Hi,

In the payment process request, the following standard report get submitted by part of the build and format programs.

After Auto Select (Payment Process Request Program),

1.Scheduled Payment Selection Report

After build payments and format instruction output program,

2.Payment Instruction Register

Is there any hook or function to change the report dynamically order by paygroup?

And Is there any possible way to do without customizing the above reports?

 

Thanks,

MVelling
