Have you looked at adding Custom Fields? You can attach a custom field to a ticket and then run a report, like a Ticket Overview Report, and "Group By" a specific custom field. Therefore, I think Custom Fields may be what you're looking for. Here's a KB article on
how to set up Custom Fields for agent use. I hope it helps.
