I can't speak for that particular radio, but I will share my experience 
with the Kenwood TM-V7A, TM-D700, and TM-D710.  I used them all on 
SO-50, AO-27, SO-67, AO-51.

I could not find any method to setup a memory channel linking both VFO's 
and allowing full-duplex.  However, I didn't ever find it necessary. 
Changing VFO's is as simple as pushing a knob on the radio or button on 
the mic pad.

For the V/U birds, I would simply tune for best reception on the 
downlink band VFO, then switch back to the uplink band VFO for PTT.

For the upcoming U/V birds, it should be a reverse of the above process.
