The closest thing to a quick save/reload you can do, if ever it is a necessity, is to fiddle with saved games. The game saves on two occasions, autosaves on a periodic basis, and saves on disconnecting/quitting. It also keeps the previous save.

1/ Wait for next autosave before acting foolishly. In case of utter failure, quit the game before next autosave. In your save fokder, you'll find your world's and character's last states saved under two .fch files (state on disconnecting), and the previous state under two .fch.old files (last autosave). Just rename/replace both .fch.old filrd into .fch files.

2/ In case planed foolish action spans over a few days and autosaves, then you have to manually copy your last stable state (either .fch or .fch.old files) under another names, and preferably elsewhere. In case of failure, just replace current .fch files by those old saved games (set to .fch), without forgetting to restore their original names (i.e. world's and character's names). This protocole is strongly advised anyways, to protect your playtime against possible file corruptions.

I believe a mod already manages saved games.
