How can I add movies to Radarr/Ombi directly from Kodi?

Ahoy! I would like to be able to browse movies in Kodi and directly add them to Radarr.

Currently I'm using the TheMovieDb Helper Add-On in Kodi for browsing movies, and then add them to the Trakt Watchlist. In Radarr I'm monitoring the Watchlist and automatically add the movies that way.

Is there a better way to do this?
For example, can I configure/use some special player in TheMovieDb Helper for adding the movies directly to Radarr or Ombi when I clilck Play? Or is there an other Add-on that does something like that out of the box?

UPDATE:

I'm working on a plugin that can be used as a player for TheMovieDb Helper. But instead of actually playing anything, it uses the information to add the movie/show to Radar/Sonarr via the API.

The PoC was successful, now I have to put everything neatly together.

I'll create a new post once the first version is out.
