Most of us have encountered the issue of teaming up for a dungeon in, for example, Olympus, Tartarus, or Darkmoor intending to complete the entire dungeon, but only to find that one or more other players only want to battle the first boss, skeleton key boss, secret boss, etc. which often leads to players needing to leave and then being penalized with a team-up timer. It would be really great if in addition to the team-up option, you could then select either "Full Dungeon", "Boss Name", or "Any" (as not to reveal the existence of secret bosses.)
Please consider adding this feature in a future update!
