request: change DF "join party in progress"

[svann]

"Join party in progress" should be a good way to refill a group quickly, and give me a quick 100 tomes. But its not worth using because it puts you in groups that are half full and waiting on more to join. Then you have to stand around in a dungeon waiting. Cant do crafting, cant do fishing. Just wait. DF should wait till it fills ALL the empty positions before sending me to the dungeon. Just like it does for the initial party.
