Does unity have a feature that lets you change something in one scene from a completely different scene?

I want to create a main menu(scene 0), a settings menu(scene 1), and a main game(scene 2). In the settings menu I want to be able to choose new backgrounds to be behind the game, can somebody please tell me how I would do that if it is even possible?
P.S. If you could show me in javascript that would be awesome, thanks.

Yes, you want to read on DontDestroyOnLoad. Say for example in scene 1 you have a GObj that is flagged for DontDestroy and based on user input you set var backgd = myCoolBackGround; on that GObj/script.

When you get the scene 2, you have the reference/variable, use it however you’d like.
