Change Respawn Room

I would like new players joining the game to spawn in a different spawn room than the others. Is this possible?

I'm creating a room that will be for players who die, and one for new members. Once the game starts, the main spawn will disable (for deaths) and the other spawn room will activate.

How can I keep the main spawn open only for new players? or simply have a special location people go when they die?

how would i go about changing the properties during game play?

also - i ran into an idea for doing this but i don't know how to apply it. What if I had a "Name" assigned to someone who crossed a trigger and then filtered based on the name?
