I want help figuring out how to change multipule sprites images by clicking a button that in another scene

In my game I want it to be that you can set a specific character as your background in the game, lets call it scene1. When you go to another scene (lets call it scene2) where it shows a multiple buttons and when you click on one of the buttons it should set the sprite image in scene1 to that character. I was hoping to incorpriate a scriptible object to save the data for each character (which I have already made and it stores sprite images and a audio) so the button should use the data to apply it to the sprites in scene1. I often see this feature in rythem games and really want to incorpreate it into my game.

I am sort of new to Unity so I apologize if this is confusing to read.
