Okay, I understand now. So basically, you can import a save that is on one route, then use the mod to get a full harem route. The only thing is you need to know when to change the variables to see different scenes or just go back and forth from the beginning, but that's a pain in the ass cause of all the sandbox stuff. You can also change variables while in sandbox mode to see different scenes. Maybe scrappy or someone else can make a list of the right places to change variables in order to see all the different scenes in one walkthrough, but that's a lot of work. I hope this helped someone.
