Multiple libraries in one collection

[Lance]

Hello,

i am currently thinking of expanding my jellyfin medias with documentaries. However i dont want them mixed with my  shows and movies, so i would want a dedicated documentaires section. Documentaires are however often shows and movies. My initial thought was to just put them in a mixed library, but the mixed library is only legacy and may be gone in some time in the future, so i am looking for a solution to have my folder with documentaires shows and with documentaries movies show up under the same Documentaries section in jellyfin.

I know this may be a niche case, but what would be the proper way to implement this?
