Eliminating a tack "room", but adding a wall of tack closets?

Totally random thought, OP, but your post made me remember the closet in an apartment I rented many years ago. It was a nice big on, that took three louvered sliding doors to close entirely. The biggest problem with it for me was that the way the tracks worked, you could never have more than one “bay” (for lack of a better term) open at once, which was kind of annoying. (I think there were two tracks that the doors hung from - two on one track, one on the other.) I ended up removing one of the doors from the “two door” track, so I could have one big opening available. The downside was that you couldn’t ever close the closet off entirely, but that’s just incentive to keep it neater… Wondering if you could adapt that somehow, like create three separate “bays” in the closet - one might need to be open all the time (but maybe that could hold basic/lower value stuff like stall cleaning tools and spare buckets), but the others could be lockable somehow?
Sorry for the less than stellar description - it’s perfectly clear in my mind!
