You made it for import, our users really need it for export. It would run as the append feature : you can choose tables to append and it creates dependencies.
With this new excel export action you would be able to add several tables and it would export them in corresponding sheets, using the name of the tables for example.
Today if you want to do that, I think you would have to create another projet and iterate on the list of tables, or use several export actions + synchronize actions not to lock the excel target file. Very complex … Especially for business users.
