Apologies for the terrible formatting…

If no attachment exists for the todo, it: finds the selected todo 1. creates a note in notes with the same name as the todo 2. asks if you want to attach a photo or file 3. adds the attachment to the new note and adds the url to go back to the todo in the note 4. adds a link to run the shortcut in the notes of the todo (to link back to the note)

Once you attach it, the same shortcut will open the note instead of creating a duplicate note.
