It should be made clear that a property is connected to Essential Graphics

It would be great if any properties that have been added to Essential Graphics get some kind of clear indication in the layers panel that they are driven by Essential Graphics, right now there is no clear way of knowing that a property may be affected by Essential Properties from outside the comp.

This indication could be an icon next to the property name, or perhaps even a "pull" button to pull the value from one of the instances where this Essential Graphics comp has been used in the project. (you would need to be prompted to select which instance to pull from)
