Automate Orbit Centre on multipanner with one parameter

I want to find a way to automate the Orbit Centre button on the VST multipanner with one parameter. The problem I have is, because the orbit centre essentially controls three other parameters (x-axis and y-axis panner, plus the rotation around the z-axis) when I record the automation, it’s difficult to edit / fine tune. Also it would be way easier to simply draw it on one automation track
