Parenting separated dimensions while keeping relative animation of layers.

[Callum Cannarella]

So I have two layers both with separate dimensions enabled. They both have different animations happening on the Y position but I want to connect both their Y positions to a master Null to layer up some extra animation. Is there an expression or a way to do this without affecting the keyframes already on my two current layers?

Hi Callum! What happens if you simply parent the layers to the null? Does it work?
