Have all players load scene Asynchronously

Hi, I'm trying to set it up so that when a player joins a room he loads the game scene asynchronously, so that when the game starts he can join near-instantaneously. If they started an asynchronous scene load operation upon joining the room, would the MasterClient just be able to send a message to all the clients saying to enter the scene when it's ready? It seems like I would need to turn off AutomaticallySyncScene to do this. Is this a good way to go about it? Thanks!
