Ability to subscribe to words and phrases

I'd love to be able to have like a little thing that would let me know if a keyword was used in an open project. There are specific franchises I really want to voice and it's tough going through each and searching individually with the advanced search. For example, I want to voice act Hello Kitty someday. If I could subscribe to the keyword "Hello Kitty" then I would be notified in the dashboard or even in notifications if a project like that is open
