Additional User Category For Videos\Media

I suspect this may be skin-dependent, but I’m curious to know if anyone knows of an elegant solution for this, and if not, to formally request it…

My Kodi setup has all of my household media imported. What I’d like to do is have a category (similar to watched\unwatched\all) where I can mark certain shows, movies and music as “owned” by a person and then switch to a list just for that person. So in other words, my wife and I watch different shows, so I want to categorize by “my shows\wife’s shows\all shows” and then map a button to switch between them (as I’ve done with watched\unwatched\all). Even better would be if those shows could be listed with some kind of marking (different colour, an icon, etc.) – although, again, I suspect that would be skin-related.)

Any suggestions?
