Find All Instances Of An Object Or Person In Footage. Feature Request

I do a lot of documentary editing with often 12 hours of b-roll. If a director asks for an alternate b-roll shot of a specific object it would be great to be able to search for that object and have all instances of it highlighted on my timeline (or created as a new sequence).

Likewise, I often have multiple interviewees, so it would be great to search all of my b-roll for every instance a specific person appears.
