Mediabay: Itunes library, Metadata

I have added the iTunes library to the MediaBay and I can see/play the songs from the MediaBay.
I would like to know, if it is possible to see the “artist”, “album”, etc… metadatas of the MP3 files in the MediaBay Filters panel. Indeed, I would like to select files in the MediaBay Filters panel by using these attributes. It is strange, because these attributes are not available in the MediaBay Attributes Inspector, but they can be used in the search field (text) of the MediaBay Filter panel.
