As a teacher, I use GoodNotes as a smart board by presenting on projector. I usually upload blank template of today's lesson in a Google Drive where students find the notes, this is the blank document to start. As I teach, I like to upload the updated version to the same folder, but want the option to have GoodNotes overwrite or replace the original file with the same name so the new version is what students get. That way I don't have to go in after to delete the original so only the new one is there.
