Revert To Slot # Blender File

It would be nice if I could revert to an auto-saved Blender file that I was using when I rendered into a certain slot.

Say slot 1 has different lighting, slot 2 other lighting, slot 3 with less/more shadows, etc. I decide I like slot 2's render the best - it would be nice to have a "Revert To ..." popup menu and select "Revert to Slot 2 Blender file"
