Any other option apart from TVDB

Ok, so I've been having a few troubles with some of my TV series, namely that series numbers don't line up to what I'm seeing on TVDB. Turns out, they're trolling a lot of series by using some random season/episode number they consider "official" as opposed to airdate/releasedate. ARe there any other options on the serviio for metadata that use the proper season/episode formats or is there some plugin that converts the stupid tvdb numbers to the correct ones? I really don't want to be renumbering dozens of files on some series because these idiots are trying to pull a Microsoft...
Or at the very least, is there a way to get metadata via the "absolute episode number" as opposed to the season/episode method? TVDB supports this for anime and they have gone and used a downright stupid approach to numbering anime that makes no sense.
