YES I need this. It could be useful for indicating things like game mode e.g. "NMPZ only" so that you don't get tons of people joining expecting NM and constantly asking for it. It can also be used for indicating the theme, like "Indonesia practice session". There are tons more use cases for this and I think it would make it much easier to see which party you want to join instead of manually going into each of them and checking the settings.
