Feature Request: Filter TMDB Director Credit by "Directed" Only

When adding a director collection on Nuvio from the built-in TMDB catalog, the results pull everything from their TMDB bio — acting credits, producer credits, cameos, everything. It would be really useful to have a filter or toggle that narrows it down to only movies where they are credited specifically as Director.

Also, is there any option to include ratings from rpdb, top posters or better posters for that particular catalog pulled from TMDB?
