Flash Builder Mobile Emulator Start-up Orientation

I am trying to figure out how to change the default orientation of the Mobile Emulator from Portrait to Landscape. I have tried setting the StageAspectRation, StageOrientation, etc and it still opens in Portrait mode. My app/project is reading everything properly as though it is in Landscape mode, however the Emulator itself is stuck in Portrait mode and therefore cutting the screen off.
Any help would be appreciated.
