I was looking at how to daisy-chain profiles and couldn't find the information in the manual, so thank you for sharing the solution!
As for changing the tabs for the Interactive Kneeboard extension, you can do so by issuing "Kneeboard... AWACS Page", I think you need to update the keywords database in the VA profile after enabling the extension for it to work properly. (as described in the manual).
You can also bind a key in the VA profile to switch the Interactive kneeboard tab page (eg. "kneeboard.tab.prv"), see page 48 of the manual, the regular "[" and "]" binds only work for the DCS kneeboard pages (not the Vaicom Interactive Kneeboard tabs).
