How to save player start vector so when player reenters a level, they are placed at the door from which they left?

I want to use a SaveGame blueprint to store vector location of a player (as a variable) when the reach a door (that takes player to a different level) so that if the player turns around and leaves, they will arrive at that saved vector location.

A screenshot of what this would look like would be most appreciated, I’m fairly new.

Thanks!
