Hey Rockum,
I scoured the routing and monitor sections trying to find a way to do as you asked, but didn't find any. The Control Room signal appears to have only three possible outputs: 1) the Control Room monitors, 2) the headphones, or 3) we can route it also to the Studio Output. There's no other place on any routing screen or Monitor screen that appears to let us route the CR output to anywhere else.
That said, how about routing CR output to the Studio Output (presuming you're not using those) and feeding the signal from them into a couple of channel line inputs or into an AUX Return? Both of those are eminently routable to whatever else you may want in any form/protocol (TDIF, ADAT, SPDIF, AES/EBU, etc.)
