@Flurrywinde11 had some success trying to link it to a button here: ChoiceScript Saving Plugin (Update: Sept. 2019)
But it’s not behavior that I ever had in mind when writing smPlugin.
It might be worth your time trying to implement it in the stats screen now though, seeing as the way that it is handled was amended recently, I believe you’re now capable of using *gosub_scene and *return within it, so wouldn’t be surprised if smPlugin now worked too. Worth a shot at least?
