Sonos Grouped Zone Volume Linking

Hi, I am playing to a Sonos Grouped Zone from Roon and it appears when I change the volume from Roon, only one of the Sonos devices is adjusted. Is there a way to force all Sonos devices in the Group to change like it does from the Sonos App? Thanks!

Ah…I see that volume is linked if I group the zones in Roon vs. in the Sonos App. Any way to add a slider for the Grouped Volume?


+1 for that
