I don't know the answer to that, but I do have contact info for the Apple education VPP support folks. Call them toll free at 1-800-800-2775 or fill out their online form https://ssl.apple.com/support/itunes/vpp-edu/. If you find out, could you post it here so we can all know how its done?
Hope this helps!!
Now why didn't I think of that - I have my Apple Education account manager's number in my contacts!
I've given him a ring; apparently it is a known issue that they are working very hard to solve, and it is one of the main reasons they haven't rolled out across the rest of Europe yet. (We're in England if you hadn't picked that up).
So for now, the answer is no, but as soon as they get it working it will be available.
