Never heard of this in the years I've been here. I guess you could set up a regular 1v1 game and then the team side could consult by pm and decide a move to be played by the one named player in the game.
Or you could do it like an OTB simul, create a single game for each opponent (playing black) against yourself playing white. Create a special folder for them and give them all a 1/0 time control. Preferably unrated.
