Finding Prefab children

Is there a way of finding all prefab assets that are based on a specific prefab, without having to go through every single prefab in the library? The latter solution is an **okay** solution, since I wouldn't be scanning often, but of course if possible I'd rather have something faster if it exists :3

 

Save all the instances to a list on instantiation.

 

I simply scan all assets, it works fine enough :3
