How to save the world as a whole with blueprints

I’ve look but only seen that when creating a save file you set up what variables to save. But we are creating a more open world building game, so we would somehow need to save the world as a whole. There wont be changes to the terrain, but things like what trees are gone, and what the player placed where all needs to be accounted for. Is there a way to let the play make a save file for all this?

This would be quite nice to know; I’m sure others are curious as well.
