I don't know if Jeremy ever got an answer, nor what the answer is, but I know that if you want to be assured that someone in OmniGraffle support sees your question, you should send it in with Help->Send Feedback. The forum will often get you an answer sooner, if another user who knows the answer happens to read it, but there's no guarantee of it, whereas every email sent in to Omni support is supposed to be tracked and answered. No harm in asking in both places, either!
