PICKWIPPING MANY LAYERS TO A SLIDER CONTROLLER

[Jimmy Simpson]

Hello AE geniuses,
Hope you're well.
I'm working on a personal project at the moment where I have about 20-30 layers per comp and about 12 comps need similar working doing.
Each layer is parented to the below layer (found a script for that one).

I need to be able pickwhip each layers rotation and scale values to an adjustment layer with two expression sliders i.e. one for rotation and one for scale.
At the momemt I'm doing it by 'hand'! i.e. alt-clicking stopwatches and pickwicking etc. Very tedious.
Is there a script or an expression line that could help automate this.

Thank you for reading this.

I don't think that a script does that.

You can try to do pickwhip the rotation and scale value for the first layer and then select "copy expression only". Select all the layers and then past.
