Bitmap layer won't follow camera

Hi !

So I decided to use a bitmap layer to sketch my animation. I had aleady imported my backgrounds for my animation and placed my camera, using a peg for camera movement. I started sketching, but when the camera started moving I realized that my sketches didn’t follow the camera movement and the only way for me to move my drawing canvas is to move it with the move tool. I tried adding a peg to copy/paste the keys from the camera but it won’t let me.

How do you get the bitmap layer to follow the camera movement ?

You animated the camera but did you ever animate these drawings on the bitmapped layer?
