tmdb: ratings for movies

Hi,

I have a video library with additional information for each movie stored in nfo-files created by MediaElch. I also rate movies on themoviedb.org. Is it possible for kodi to fetch ratings from my account at themoviedb.org and to show it for any of my movies after updating the library?
What about the other way round? What do I need to rate my movies in kodi and to save the ratings automatically in my account at themoviedb.org?

Thanks!
