Automatic Tagging files from Non-NC users

Hey NC community,
Thanks for being such a great resource! Is it possible to automatically tag files that are uploaded by non-NC users? A generic upload link is sent out and I would like the files that are being uploaded into NC to be affliated with a tag automatically. I know there is a Automatic tag feature in NC, but I’m not sure if it has this specific functionality that I’m looking for. I am currently running on NC v15.
