Thanks.
I did initially miss the post, but the person I talked to at the training center said the same thing. There is someone at the training center who can do it but isn't the one working today.
I had figured I would try getting the agent to do it when I got to the airport anyway and as a last resort just get the bag and recheck it. While a pain, KCM would at least make it doable.
Good to know I was on the right track.
