HEOS add support for Denon Home Subwoofer

I really want to see full support for the Denon Home Subwoofer. The subwoofer is in my case connected with the Heos Soundbar. Allthough recognized by HA there is no possibility to change volume, bass level, …
If this would be supported then it’s also possible to adjust several settings for the sub. Now i have to manually change these levels through the Heos app which is sad.
When watching tv the bass level is set to low but when i listen to for example vinyl then the bass level must be set on max. This would easily be configured in an automation if there was support for it.
