How to rewind?

I searched the tutorial page but could not find a specific feature in Ink language to rewind to previous stage of the game. I want the player be able to rewinds to his last selection every time he/she rewinds.

It seems I can probably do a workaround by saving each stage on disk and load when the player rewinds but this solution is not elegant. Another possible workaround probably to have an additional option that always rewinds to the previous selection but that still would not be elegant.

How did you guys add the rewind feature in the sorcery game series?
