While taking notes in the Review Notes App, you may want to upload a File (e.g. image reference, sketch, annotated frame, reference movie, etc.) to the Note.
Although we do support this via the "Send Note Now..." option for each note, you may prefer instead to upload file attachments across multiple Notes and then batch create these Notes in the next "Preview and Publish" screen. If you're interested in this feature, please cast your vote here.
