We used to do that but it not really feasible as that is saved in the client and weird things happen when folks get overly complex and the client device looses memory, of the server and thing eventually get out of whack. Server admins also expressed interest in adding the rows they want the users they gave library access to see which is done based on collections that can change arbitrarily whenever the server admin wants… That is why it is controlled by the server admin not the client.
This is also the same as this suggestion which i don’t think will ever happen but you should vote on that one to not split votes.
