Interesting question. I cannot see any reason why they wouldn't, in theory. But there are rules that need to be followed; I think it might come down to hoping you get a more imaginative CM at DME check-in upon arrival. I doubt that the DME person on the phone would be able to help with this; I expect you'll have to work this out when you arrive at the DME counter.
Hey, and if you aren't able to do it, just take the DME bus to POR and cab it over as Brian suggests.
I hope it works out for you!
