How to get another parameter to follow same automation

hey guys so I have 2 whammy vst pedals (inside Gojira X) and I want to trigger both of them using 1 automation instance. How does one do this?

Background: basically I have guitar L & guitar R which each have their own whammy pedal.

Are you doing this on two audio tracks, so two instances of the guitar plugin?


You can only copy automation over in that case.
