Modify Customer Payment Journal Report

Hi Experts,

Hope you guys are doing great!

I would like to adjust Cust payment journal report size to landscape and I need to add Grand total field.

As per standard AX, retain the functionality of being able to run this report before or after the journal is posted.

So where can I go there to find that report, how can I adjust the size and add field to that report?

I really appreciate your quick response.
