How to combine filters from multiple libraries?

I have all my movies divided into different libraries, and I’m very happy with that solution, and would not have it any other way, but I want to use filters to search for a specific actor / actress or a specific director in all the libraries in the same search. But it does not seem possible.

Would it be possible to add a function to the “custom filter” to have the ability to search different or all the libraries?
