Copy and paste layer positions in 3D space

HI there-

I have a few scenes that I applied a “handheld effect” to by moving the camera slightly.

I’d like to add parallax, and the scene is already done. How can I copy/paste exact Z position and Layer scale from one layer to another in a scene? I have a BG, a subject (midground), and a foreground.

I just want to push the foreground closer to camera and scale it down, and vice versa to the BG, but there is animation in the layers themselves, so the position and scale needs to be the exact same for every panel…
