Load state shortcut?

Hi, is there a way to save at a point and then load again at that point?
For example, I am making a figure and I save the state at that point, then I make many changes and I want to undo them again and I want to go back to the point where I made that save but without using “Open file …”.

I mean, a shortcut to load by pressing a single key to go back to a previous saved point in a quick way (without using undo repeatedly and without going to “Open file …”).

The snapshot docker provides that, but once you save and close the image, the snapshots are gone. You can also use save incremental or save incremental backups.
