Connecting 2 UR816C Units Together

Is it possible to connect two UR816Cs together into a single contiguous audio interface in Cubase 10.5? If so, what are the connections and are there any issues?

Thanks for any help on this.

Bump…Did you get an answer to this question since I want to know the same thing, the manual describes HA mode but also shows a diagram with a usb cable running from each unit to the computer.
