Handling multiple versions of imported movies

I haven't been actively using Channels for my imported content, but with the nice changes earlier in the year (and all the crap going on over at Plex), I'd like to try again. Just wondering how people are handling multiple versions of the same title, but with different resolutions (4K vs 1080p for example)?

I know by default they show up as separate movies - is there any way to add any kind of overlay to the poster to indicate resolution, etc. ?

The other thing I've thought about is creating a Movies personal section that excludes non-4K content when I have a 4K version, but not sure how I could do that without adding some custom tags (need to keep the non-4K version available for when I'm on a lower-end device).

Just wondering what others have done?

Well, I only have a few 4K movies now, but I just add it to the title. If you have a larger number that may be too tedious.

You can find posters for movies that have a 4K badge or header at the top that say 4K if you want to manually change the posters. You can find posters for downloading on TMDB, theposter.com, mediux.pro and I am sure there are other places. That could be a solution but may be some work to change the posters.
