I saw Stefan's post on the ISG forum and gave it "the old college try."

I placed a glass HSI in the VC with a reuse of the GPS popup window to trigger a single window containing both the MCU and HSI controller - http://fsbuild.com/forum/viewtopic.php?f=4&t=1689&p=14081&sid=e6ff938f0928c9aef0e2d17483bc8933#p14081

The popups' positioning could be improved upon with no doubt, and I've since separated the MCU and the HSI controller into two popups on my system.  But it's something....  :-/
