Configuring additional AI Cameras

FSX supplies a global camera definition (cameras.cfg) that views AI aircraft in spot view. I've been looking for ways of adding additional cameras with alternative views, such as tower, flyby, etc. However I have not found a way to do this in the global cameras configuration. It seems FSX will only allow one definition in there with the "AI" GUID, and any other definitions with different GUID's don't seem to work.Anyone else worked with cameras or can make suggestions? ThanksSimon
