Change Anchor Point of Directional Lights

The default anchor point for directional lights is the model origin and the direction around that point. It seems that the light has a fixed distance from the anchor point and it prevents me from illuminating the top of my model. Is there a way to move this anchor point or extend the distance from the point? As shown in the picture below, the light with the arrow cannot light from above the model and all 3 lights are anchored on the bottom right corner. If it is not possible to modify this, would a point or spot light have more flexible settings?



I'm using SolidWorks Premium 2014, if that is relevant.
