Eject RDX after synch Job

Hi, I use RDX to backup offline my secondary PBS server datastore. I've un RDX charger and I would eject the cartridge after synch job as finished successfully. Is possible to add this functionality on synch job for removable device (or for all type of synch job) or add a post script launcher to add command to make action after synch job terminated successfully (or not). Thanks ...
