How do I make a spawn pad only spawn players once

I am making a racing game and I want players to only spawn once at the car selection Then spawn at the track selection

You could probably use teleporters for the car selection, and then you could use actual spawn pads for the track, teleporting you once to the car selection.

Grab a spawn pad and a lifecycle when player knocked out teleport and put the teleporter where yo want it

That would work thank you

Add a respawn device or add teleporters
