This new generation of VRs seem to have added that to their arsenal. I noticed the same thing between SR Mk2s and Mk.3s, VR-5 SEs and Anniversaries. Now we're getting word that the Jr2 and Jr3 are doing it too.
I wonder if the work on the UNIs had some indirect influence as all UNIs I've had on hand have had the ability right out of the starting gate.
Thanks for the pics Scp, I see a strong family resemblance to the VR-35 Ex drivers.
