Is there a way, either within Vegas itself or by means of a 3rd party plugin, to change the view of panning/cropping/rotating?

Vegas currently shows the input, with an outline of what the output will be. I would like to see the output, with an outline of what the input is.

Trying to precisely correct random rotation by hand is difficult with the current arrangement. I think I have it right, but when I play the result, it isn't. If the camera is tilted up, a vertical pole on the left or right of the frame will tilt inwards, and trying to present that correctly when the whole thing is randomly skewing on the screen is a nightmare.

The alternate view would also help while trying to correct or apply panning, as well.
