Animate_ Disable camera on SOME pegs?

Hi there, I’m just started with toonboom animate (the learning version),
and I’d like to ask if it is possible tob enable the camera on only part of the pegs?
Here is my case: I’d like to use a reference mov for the camere movement itself, but if I’m moving the camera, naturally the reference mov moves within the frame. Which is not good.
I’m sure there’s a pretty easy solultion to this, only I don’t know it.
Thanks for your help!

Just make your reference movie a child of the same peg that you use to move the camera.
