It would be very useful to have a way to identify references vs target files on the delivered services (ie checkbox to mark a file delivered as "reference").

Sometimes providers need to deliver reference files (ie checklists) or PMs need to deliver reference files to customers along with the actual deliveryThe  step should include a check box to mark certain files as reference files and not target files of the delivery.

This will help in excluding them from any reports on delivered files and would set a base for these files being/not being included on post delivery validation cycle (typical use case would be translation certificates which need to be included on the delivery but do not need to go through post delivery review cycle)
