Adjust Camera(s) Just Like an Object
What would be AMAZINGLY helpful if the "Snapshots" are saved as individual cameras. When you create a new snapshot it creates a new camera. Once you move away from the position you see a ghosted camera that you could manually control (position and rotation). Once you've made your adjustments, you can double click on the snap shot and that view is updated. If you want to have multiple snapshots, you'll see multiple ghosted cameras in your skybox.
