Does Amazon now have a way to search for Registered Brands before a Seller chooses to sell something???

I am working on selling a brand I created and I have already registered it with Amazons Brand Registry. Any factory can copy it, but not rightfully in some instances. This may not benefit them either as a trademark/brand owner holds they key on a marketplace.

If I ask a China factory to make me 1000 units and they choose to make 2000 units with the intention to sell distribute the extra 1000 on their own then that may not be good. Furthermore, what good would it do them to do something like that if sellers now have brand registry tools where they can shut other ads down for selling copies and stuff?

This brought me to wonder if Amazon has a search tool yet where any random seller can go search for a specific protected brand name to see whether or not it has already been registered/protected and hence worth their while to try and sell or not.
