App/process that can show a list of tasks pulled from within my notes?

[waykokid]

I'm a guitar teacher with a Galaxy pro 12.2. I use the s pen to take sparse notes during my private lessons. Occasionally those notes are tasks that I need to accomplish (make copies, send email, etc.). Is there any app or process (ifttt maybe) that could pull those tasks out of my notes and show me a list? Going through the notes for all 35 of my students and looking for tasks is rather tedious. I'd be happy to tag them or enter some special symbol or something in my notes whenever I made a new task. I beleive you can make outlook tasks within onenote in a similiar fashion but none of that functionality is included in the mobile app. Any help would be greatly appreciated. Thanks.
