Hey there, glad to hear the tool has been helpful! For making your own lists - you won't be able to use the built in Achievement.all_achievements list since that includes all the achievements (it's in the achievement_gallery screen in the line for a in Achievement.all_achievements:). But you're welcome to make your own list! For example, after the achievement declarations in the example, you could do
define chapter1_achievements = [ sample_achievement, progress_achievement, set_progress_achievement ]
and then you can copy the achievement_gallery screen and replace for a in Achievement.all_achievements: with for a in chapter1_achievements: and similar. If you're screen-savvy, you can reuse the achievement_gallery screen and simply pass in the list you want to loop over as well, though copypasta works just as well if you're not familiar with those! Hope that helps ✨
