Some good news to report that after reviewing various posts in the Logitech Squeezebox forum, I was able to make two setting changes that allowed me to use Roon to play thought my HEOS Link and HEOS Drive, as well as Sonos.
During that process I discovered that the names associated with devices seem to not be stored on the Roon Server but must somehow be recorded in the Roon Apps as all the UPnP devices show under Squeezebox as UPnPBridge. Odd, but workable through trial and error.
