Pro Link w/2CDJ2000NXS + DJM 900NXS2 + 3rd Deck Via DVS

Seems convoluted, but basically do not like using HID Mode.

I'm trying to mix the way I usually do... which is the source via USB directly on the CDJ (and connected the second CDJ via LINK).

Now, I would like to incorporate a third "deck" while maintaining sync-abilty between the three.

The idea is to use one of my turntables with TC vinyl (dvs) as the "third deck".

So far, doesn't seem like this is possible.  I am using the DJM 900NXS2, and the CDJs+Mixer are connected via USB, and ethernet/switch.  With laptop connected to mixer via USB.

Any thoughts?

Thanks in advance.
