As a teacher, I use GoodNotes as a smart board and do work in class, I upload notes to Google Drive for students to see later. I continually upload notes as certain parts of a document. I would love if at the start I upload the note to Google Drive, and part way through the lesson I export again to Google Drive, that the orginal one in drive is overwritten so that the new one is there for students. This way I don't end up with 3-4 files with the same name and have different things in them and students have to figure out what one is the newest one.
