How to save changes to a scene when moving to another scene

I have two scenes that the player will switch between regularly while playing and changes will be made in both scenes as they play. If the player moves an object in scene A and then moves to scene B, when returning to scene A, the object is where they left it.
From my perspective this should be relatively simple and common. I can even think of a few ways this could be done, but after more than an hour of searching for how to do this online, I am no closer to an answer. All of the tutorials that I have come across are for preserving an object so that it follows the player into the next scene.
Any advice would be greatly appreciated.

Is there any specific reason you are dividing this into scenes? Would it work if both scenarios are in the same scene? Maybe you can switch your camera accordingly. So in this case, things will remain as it is. Although, if there are too many gameobjects/ui elements etc. scene size would be large.
