I did that in Serenity Chapter 1 and it was such a huge pain in the ass I just chose not to with Chapter 2 or with Last Human.
However, when I get close to finishing both projects, I plan to add an episode chooser and also a 'lewd scene' player. I hope that is some consolation at least!
I totally understand that thought process. The work and effort you are putting into the game is hugely appreciated, every aspect of both this game and Serenity is just incredible. The overall story, the writing, and especially the characters are wonderful and i ravenously consume every new update. Thank you for the response, and if you ever do find put a replay function in I'll joyfully use it!
