Unfortunately that's just not possible - there are hundreds of choices tied to variables in CK. Skipping without setting these would completely break the game, and setting up a "Did you do X or Y" choice list would take about twenty minutes for players to get through and likely would accidentally miss some anyway. It would also need to be updated every single time there was a new choice to make in the game, not to mention the sheer coding insanity of allowing players to choose what to skip and what to play through. CK is not a linear game - it's a sandbox ;)
For a AAA development team it would be difficult to the point of impossibility (There's a reason you don't find skip functions in games like Skyrim). For a solo dev on a weekly update schedule it would be like trying to high-five the moon by jumping really hard.
