With the Annex, Andrew meant the attachment to that post (see the link under the message tekst).
It is a *.bgl file you need to store in the addon sceneries folder of your FSX install, and things should work.
Have not had the opportunity to try it out myself, yet. But with 2 succesful attempts, things are looking good...
[EDIT]
Tried the workaround myself, and it worked as advertised

Working on a structural solution, but in the mean time, this BGL solution is the way to move forward.
Thank you, Andrew!
