Hi bassimbg ,
Sorry if this doesn't meet your needs.
However, you can dynamically add and remove a filter before and after the export process (just play with the priorities of the hook atum_export_run_export_"template_id").
I am just exporting from the site itself, and its putting it in random folder inside "atum-export-pro", sometimes with folder that as number or in tmp...
In the same way that we use above the template_id to generate the filter's name, we also use it to construct the path. So it isn't a random folder, it's the template ID. Of course, if you're creating the template from scratch, we don't have an ID until we save the template, and we use 'tmp' then.
Anyway, I will discuss with our team the possibility of allowing to change the whole path with a new hook.
Best regards,
José Andrés
