How to rotate GEOM_BOX about its end instead of center of mass?

Hi there, I want to rotate a primitive shape, a p.GEOM_BOX, about its end, instead of about its center of mass. A very simple standalone chunk of code is here https://github.com/MachineLearningLab-AI/PyBullet-Hand-Example/blob/master/finger_demo.py Pressing 6 or 7 on your keyboard attempts to rotate...
