Welcome to the forums! Just wanted to let you know that (if you haven't done so already) emailing your question to our support ninjas is a good idea. We all browse the forums as we're able to on top of our other duties, but we can't guarantee that someone from any particular team will see a post right away.
(In this case, I saw your post, but I lack sufficient Visio- and OmniGraffle-Fu to answer the question.)
If you email the
support ninjas, you're going to get a fast response from someone knowledgeable about the product you're inquiring about...
