Yes, it is.
Click the "Show Points" button (the one with a red dot and a black line). Look inside the cockpit, you should find two red points. One is helmet position and the other is the focus point for track camereas. If you import the shape from gp3.exe, you can show helmet shape as well, but beware: the points mentioned are reversed in car editor. So when you change helmet position you are actually changing the focus point and vice-versa.
