The answer to your question is yes. But before I can give you all the details I'll have to do some work getting computers set up as I'm dog sitting at my brothers house for the holiday. I discovered the process while working on my latest flightsim movie just yesterday..
The process can be found in the SDK if you have access to it, under the topic of creating custom camera views.
What you do is create a Flight file or ".FLT". Open it with a text editor and add as many custom cameras as you like. You'll need to know the Latitude and Longitude and how high you want the view to be above ground level. You'll also need to convert the Lat and Lon into decimal format.
When you start the flight and go to the view menu, there will be a new camera category called "custom". If you have more than one camera, you can cycle between them by using the A key.
The good thing is that you can create these custom camera locations without having a copy of any of the scenery files involved, you just make your modifications to a saved flight file.
In the SDK there is a sample text file that shows how to make the text entries.
More info to follow:
