Hi,
We don't have anything on the short-term docket. You could, as a workaround, either paste or save the CaseComplete diagram as an image and paste it into a visio diagram. This would have limited editing capability in Visio, of course, but if these are static this might be a reasonable approach.
Sorry I don't have a better answer than that right now. The vendor we use for our drawing surface has started to provide some rudimentary Visio capabilities so this may develop into something more robust that we can take advantage of in the future.
