Change value of ' BtchBookg' tag in Dutch Sepa-file export

Hi there,

With the Dutch telebanking module you can export SEPA payment files (xml). A client of mine wants to have the value of the tag ‘BtchBookg’ by default changed to true. My first thought was to copy report 11000012, but that report uses a lot of variables that are not allowed because I’m targeting Saas and not OnPrem:

Is there a better way to achieve this?
Thanks,
