I wondered if you meant this, it’s always hard to tell which level to answer a question on.
Problem is the engine is looking for a player start, so the only thing you can do is copy it and change it. Using it as a parent wont work of course.
It sounds a bit like you’re using level streaming there?
For that, I put the player start in the map, stream the level and loop until I can see the player start, the make the level visible and spawn the player.
