Z sorting of Handles

I was wondering if it is at all possible to order the drawing of handles by distance from camera.

I use handles to draw nodes of a graph and the nodes are drawn one after another and overlay incorrectly.

The first image shows a graph with 4 nodes. The node in the top left is further away from the camera. (It is smaller)

The second image shows the smaller node in front of the bigger node.

Is it possible to automatically order the handles by z distance from camera?

Thank you very much.
