Make program cateogies dynamic based on XMLTV files

My XMLTV list includes many categories that Plex ignores. Please dynamically build a set of categories from the XMLTV file, and allow the EPG to filter based on those categories rather than the fixed series, movies and news categories.

+1 please implement it, i miss 10 12 channels that plex epg dont have, i use webgraplus to generate my omw epg but plex ignore the categories and mess all under movies categories.
FIX IT please
