Plex, emby: possible to show only "server playing" instead of "client playing"

Hi,

When playing something on Emby/Plex, the “now playing” is nicely displayed on hass.
However, with a lot of browsers, devices, users, it becomes a mess:

Is it possible to configure hass in a way that is displays the item(s) playing from a certain server?
Or can hass automatically hide the unused cards (running lovelace in automode)

kind regards,
Bart
