Attaching an object to a camera in Matinee

Greetings all!
So I am just learning Matinee and I am making a space ship launch scenario. I have the camera launching but now that I’m getting further into it I’d like to attach a spaceship cockpit to the camera. However, I’m not really sure how to do that. I tried attaching a proxy to the camera and it just disappears once matinee begins. Any help would be greatly appreciated, thanks!
