Spawning interiors

Do anyone know if it’s possible to spawn interiors like a prop (server side) ?

I too want to know how this is done. I have heard whispers of people succeeding.

I know that many of the interiors are in the map at -99 on the z plane

I think I heard something about “interior hash” but not sure if thats real

edit: searching the fivem native reference for “interior” does indeed turn up a lot of functions that deal with interiors (and the hashs) but so far I cant find a single one that actually SPAWNS an interior at some other coords
