Only one respawn per round

Hi every one,

I’m new creator. I’m using creative from playstation.

I made fight map 5v5 which had 3 rounds and 2 teams.

I want that the dead player turns to spectator mode which can sea his players team who stay alive. I tried to set spawning times is 1 time in map settings. But this option will respawn that player from sky at next round.

I want to set spawning times 1 time per round. How can solve this problem?
