It is fairly simple, though, to focus and take scenes online remotely using simple scripting and RossTalk. In that way, instead of one scene triggering another Xpression, just use the scripting to take both online at the same time. Perhaps not an ideal solution, but it works (we use a more sophisticated Python script with a UI to do this in house). If you have someone handy with python, or another scripting language, it wouldn't take much.
