Stop notifications for specific items

While viewing an item (idea or feature, for example) enable to control my notifications of that specific item. Today, I have to go to notifications and find the item to change notifications. Interestingly, there's neither a search feature nor reference IDs to search for -- just titles.

This would help me because I touch a lot of items as I triage them for other people to work on and then I subsequently get notified of every comment and change.
