Block child canvas position when moving parent

Since the game I'm working in will have multiple playable characters (you can switch character when you want), I needed to make a canvas, with the health and resources bars, for each character prefab.

The problem is that, since I actually move the parent object's transform with my PlayerContoller script, the canvas and all UI elements I have on it moves as well.

I tried setting the RectTransform of the canvas equal to an empty gameObject's RectTransform which is located inside the canvas for the general UI, through a script that simply assigns on Update() the specific UI canvas RectTransform equal to the one from the empty gameObject.

It worked, but I would like to know if there is a better solution for this.
