Hasta La Motion!

I would like to parent a parameter to an other.

It’s easy for example to take the multiply from a grade and with ctrl drag and drop into an other grade;

My questions is, how can I parent a panel like channel or depth. I would like to change the channel only one time and it will change it for several nodes.

I’m not looking for a python command in a script editor but I would like something similar than parenting, changing on a gizmo control once and it will change every node inside the gizmo.

Thanks for your help 🙂
