ctorres If you're trying to filter the tickets that appear in a custom queue, then yes, this is easy (I suspect a terminology clash here - filters in osTicket generally refer to actions that are taken on a new ticket as it arrives, whereas this is custom search criteria). It can either be a personal queue (unique to each agent) or one created in the admin panel - generally you just add the conditions you want to the list, as shown below:

All tickets in this queue would then be 'filtered' to ones matching all of the criteria I've specified in the image (which would probably be none given I've just selected random criteria 😆 )
