Que for in progress (save a friend or LSmate)

[StouterTaru]

Would it be possible to create a system for aiding a friend or LSmate who is waiting for the party to refill in progress.

Tried three times and then ended up with the 30minute penalty.

Instead of queuing the entire roulette, just queue the single dungeon they are doing. That is, if you really want to help your friend instead of, "Yeah I'll help you if I can also get my roulette bonus for doing 3 minutes of dungeon."
