Slicer Crop Volume ball size

Hello
I want to change slicer crop volume ball sizes in order to make easier to crop volumes, is there any way to do this ? is there any way to do this by code ?

Ball size was defined in pixels in Slicer-4.8.1, which made it too small on high-resolution screens. The issue is fixed in recent nightly versions of Slicer, where the size is defined relative to screen size.
