How to load player at other locations with world composition?

I would like to use world composition to create a large city, it works very well most of the time. But my player always spawn at 0,0,0 or at the first PlayerStart element.

How could I create a menu to select where player should start, like selecting the desired PlayerStart or an empty actor? I mean not how to create a menu UI itself, but how to select where to spawn the player on first run.

I’m researching about it for several weeks and found nothing on how to do it.

By the way, is there a paid course or training about everything related to open world with Unreal? Most courses on Udemy or similar websites don’t cover the world composition section, and I found the documentation a little bit confusing.
