DRL's "Scandinavian" Setting. (Rear lights on)

Talking to my dealer about getting the DRL's set up so that the rear lights come on too, which I believe is called the Scandinavian setting, as those countries require rears on too. He knew nothing about how to do this and didn't think it was possible.

My understanding is that a setting exists in VCDS to do this. Does anyone have any detail on where in VCDS this can be found, and what the settings are, so that I can tell my dealer?

Can't see the point in just having lights at the front and, if I must use DRL's, I would like the rears on too, especially the rather nice LED's on my GTD.
