Android - Adding New Device Profiles for Game View Aspect Ratio

I have an Hp Touchpad running Android that I’m developing on; It has a 1024x768 (4:3) aspect ratio. This ratio is not available in the pull down menu of the Game view inside of Unity 3D, instead there are a number of popular device profiles. How can I add my own custom aspect ratio or device profile such that it is accessible in the Game view?

Sadly I do not know of a way to add a profile to the drop down. The only way i have found to get around this is to go into free Aspect and move the window around with stats open until it reads the proper resolution. I also have not found a way to save them once you find them. Maybe someone has a better way.

I hope someone knows how to do this properly.
