Increase the size of the wrist strokes

Hello

In the Tracer sketcher, a tool uses the wrists. But these cuffs are too thin and therefore not very visible.

In Options --> General --> Display --> Visualization, I found out how to change the color of the handles.

On the other hand, I don't see anything to magnify the thickness of the wrist lines.

Is this possible? And if so, how?

Thank you in advance for your help.
