Change the pivot parameter of an image in fusion

In Fusion I have an image, and I would like to move the pivot to have a zoom axis corresponding to the hexagon, and not to the global image. If I use a transform, I can't move the pivot, without moving the image. What is the solution ?

use a transform tool
adjust the pivot point parameter

some tricks :

Short answer is to use the tab key to cycle through your controller gizmos in the viewer. When it gets to the red X, it's your pivot. Then move it to where you want. Then cycle the controls back to the two arrows. Now your picture center will be the X not the arrows.
