"Locked" view panning across multiple virtual cockpits

First, the setup:FSX + Acceleration, Win 7 Ultimate, nVidia GTx-8800 driving two 28" displaysBy creating a new VC window, undocking it, placing it on my second monitor, switching back to full screen, then panning the view so it's appropriately offset from the main view, I can now create a fairly realistic wrap-around view out of two monitors. This works well and the framerate is acceptable.What I'm trying to accomplish is some way to "lock" view panning across the two Virtual Cockpit views. That is, I'd like both views to pan left in unison when I hit the hat switch left, and return to center when I'm done. I know I had something like this setup in the past, but I can't for the life of me figure out what the option was.Any thoughts?
