Hi Jeff,
I’m not a user of the app, so I hope this helps ,because … I don’t know if you have an example, and if Justin shows there one and a simpler version, but I put Angie myself, but that was grade 4 and at the high end of that “spectrum”
Angie Fingerstyle
Maybe give it a sniff because it is so tasty 
, and as your technique improves, keep coming back (that’s how I did it a while ago but there is a lot where you have to "replace"notes 
… )
Be careful not to go too far above your level, but as is often the case, Justin often has a detour for difficult things, either you come up with one yourself or you ask in the community 
Greetings and have fun ,Rogier
