This is likely not going to be possible per player because it would be a networking nightmare. I can’t find the specific explanation from the devs, but the gist is everyone would be sending each other their own offsets with the worst case scenario being O(n^2). Basically, EVERYONE sending 63 copies of their offsets, one copy for EVERY other player of the server.
63 copies from player 1 + 63 from player 2 + … + 63 from player 64. You can kinda see how this can get bad quickly.
This isn’t a problem with offsets being done by the Workshop model uploaded, because its just packed into the download for the model & cached afterwards.
This is covered here already also, among other workshop improvements
