I think it's available for S3, but regardless, I don't know why the mod still has the "All" option, because it's is the main thing in this game that just will not work. You cannot be on more than one of those paths, and the only way to make it work would be to rewrite a decent chunk of the game's coding so the flags don't interfere with each other, etc. And even then, the story wouldn't make sense, so the only benefit (seeing it all on one playthrough) would be the same benefit you'd get from using an unlocker and just looking through the gallery scenes.
