multiple sources

Hello everyone here is my scenario.

My brother and I live in two adjacent households and we each have a network attached storage device that are sources to our two kodi players. We each have our own library of movies, some of them are duplicates. I would like to request a feature that deals with this in a very easy way, for example a source selector.

Lets say my brother and I have both the movie: Terminator 2

It would be nice if the Movie will appear only once in my movie section and upon hitting the play button a popup will show up with the question from which source i’d like to plat it.

Thanks fellas!

cheers
