Would love to upvote this… Troops that migrated recently to TT are “SOAR-ly” missing this functionality. The groups concept goes beyond just custom mailing lists - also consider event invites, chatterboxes, privileges, etc.

We tried treating groups like patrols in TT, but it created way too much clutter and chaos across the site in tables and reports (for example, sorting or grouping by patrol), so we reverted to strictly treating patrols as patrols and using manually maintained custom mailing lists.
A thought… could user-defined (freeform) configurable tags be tied to user profiles to key off functionality? E.g. I specify the tags “oa”, “committee”, “plc” tied to a user’s profile and they would automatically be added as options to custom mailing lists, chatterboxes, etc. later on?
