Barcode scan without entry in session list ?

Hello,

Quick question : Is it possible to run the omnimm -repository_barcode_scan command without having a session created in Internal Database / Sessions ?

The reason, I created a script that do the scan every hour (maybe a bit overkill, I confess) because too many backups waited on a mount request in the past. But now my session list is polluted by all those Media sessions I have no use of.

I checked the Command Reference PDF but found nothing.

P.S. : If you have other suggestions for my mount problem or Media sessions, I'm all ears.

Thanks for your help.
