I know that Faithlife has gone to great lengths to add denomination metadata to commentaries, which we can access via the Commentaries section in Passage Guides and Exegetical Guides.

(Incidentally, weren't they also doing this for Systematic Theologies? How come we can't access these by denomination in a Theology Guide?)

But that was just an incidental question.
My main question is: is there any way to filter the library based on this denomination metadata?
