It is possible. The problem is that you can't manually add/remove players to this game - so if i add option to create a team game with only open seats(that would be pretty easy) you won't be allowed to invite players by "add or remove players" and you will be forced to give people link to it so they can join(or anyone from the lobby). Alternatively people to invite could be passed to the script, so it can create game with them, but that would require a bit more complicated GUI.
