Multichannel Amps - control volume with Roon?

NAD CI 580 BluOS™ 4-zone stereo digital preamplifier/network player [Resolved]

I just installed Roon Today! I am running a ROCK NUC. My audio endpoint is a “NAD CI 580 BluOS™ 4-zone stereo digital preamplifier/network player” Although Roon recognizes this device in the Audio Setup, it only is seeing one BluOS Zone and not the other three zones. This is preventing me from using Roon to control music playback. Help?
