Notes to Flashcards Generation

Right now, flashcards can only be generated from the source, which I usually upload lecture slides to. This helps to generate a very good formatted summary which I just edit along during the actual lecture. However, there is no way for me to generate flashcards from this set of notes already in memo cards and i have to copy out the notes to then regenerate it as another source which is inconvenient. Hope this can be implemented!
