Is there any way to redo turns in singleplayer?

[FaceLess]

It is not even necessary to copy the saved game folder to another location. I use control c and control V to get a copy of the folder with the gamename. When you want to replay a turn delete the current version and remove the "copy of" part of the duplicated game. The “copy of” files do no show up in the game list when you open a game thus also no cluttering of games in that list
