Move movie from one source to another

Hello

I have the following use case for xbmc: one source with my movies and one source with preferred movies (these are movies that I like to backup). Both sources are on my NAS, in different folders.
The problem is that I know if I like a movie or not only after I see it Therefore I'd like to "right-click" on it and say "Move to Source_For_Backup".
Is it possible currently to cover such scenario? Or do I have to dive into writing some addon/plugin to add the extra option in Context Menu (if this would even be possible).

Thanks a lot for any advice
