This has already been requested several times in this thread:

Plex Forum – 15 Sep 13 [Implemented] Server-Side Speed Limits/Caps for Shared/Subscribed Users I saw a feature request somewhat similar to this but it was ultimately too convoluted, disorganized, and old to bother "liking," so here it is in a more streamlined post that covers the different applications and reasons to implement.

But I think it’s a good thing that this has been restarted again, because I think you ignore the old thread anyway, because a part of it has been integrated. It was also said that the service would be extended more and more, but so far nothing really new has been added for months, although it would be one of the most important components for the service.

I would be extremely happy if you could finally set this on the server side. Many of my users are often overwhelmed, although I have created some nice instructions for each app, which you have to adapt. It would be much easier if the server had full control over the shared users and could manually adjust everything from picture and sound. In this way, the Plex experience could be perfectly optimized for all users.
