SkyTeam - Using KE Skypass Miles To Book On Delta

Is there any way to book a Delta flight and pay for it with Korean Air Skypass miles other than by going through Korean Air's website?

Been at it for two hours with no success - this is beyond painful.

Considering the pitiful number of seats that DL FFs have access to at low mileage rates on DL, I'm guessing that it's going to be insanely difficult for any partner to get a flight on DL, since they can only get low mileage rate seats. Try calling?
