NFO Updater for Rating

Hello 

There is an excellent post here: 331592 (thread)
Which I have got working, thank you Karellen

However I am wanting the same NFO update through Kodi for ratings for a bespoke TV show which isnt on tvdb, I have made NFOs in Ember and basically want to watch.  Press 'i' and select my rating... 1 to 10.  I then want it to write the rating to the NFO.  So next time I install Kodi on my QNAP then I can just import these series and NFOs.

That is what I want to do and why, does anyone know of a plugin to fulfill the above?

Thanks for your help
