XF 1.4 Can I modify a user's "watched" settings?

I have a user that is claiming they are receiving unwanted emails from our site whenever new content is posted in a specific forum. The user has clearly selected (intentionally or otherwise) to "watch" the forum, and has opted in to email alerts too.

I have tried to explain how to fix this, but they seem incapable of doing this. Is there a way for me to edit their watched settings directly?
