Negative tags don't work in Watched tag list

It’s not possible to specify your watch list by excluding tags (like ‘-comic’ or ‘-animated’).
 
Is it planned to be changed?

You can’t do that anywhere other than search.  
If it were changed, I would hope you could just use search terms for tags in settings.

It’d be nice, but it’s very complicated for us to allow (and would currently blow out our plans for client-side filtering/spoilers).
 
So it’s not likely to happen for now.
