Hello Thomas,
in the transaction FBZP - Payment methods in country the format is assigned to the payment method.
This is then valid for all house banks of the company code.
Since note 1943453 - PMW format depending on house bank and company code, message BFIBL02170
https://launchpad.support.sap.com/#/notes/1943453/D there is this new possibility.
Otherwise you have to describe more exactly what you want to do.
Many greetings
