Try this. 1.Starting from behind the ball and in line with where approximately you want your feet to be at address 2. Walk forward keeping your eyes on the target or an intermediate target 3. While looking at the target set your feet 4. Without taking your eyes off the target allow your body to settle in 5. Now look at the ball and adjust for ball position and reach without changing your alignment.
This works amazingly well provided you do not look at the ball in the process, until you are settled (trust me you will not walk past the ball). I have had countless students do this and they are spot on to where they need to be.
