This is a case where OpenStudio allows for more flexibility than EnergyPlus.
EnergyPlus only allows one Daylighting:Controls object per zone. That object has fields for up to two reference points but only has one field for 'Glare Calculation Azimuth Angle of View Direction Clockwise from Zone y-Axis'. Reading the Engineering Reference I'm not sure if glare calculations happen at both references points or not.
When using Radiance for daylighting calculations, OpenStudio is not limited to two daylighting reference points for each zone and it is not limited in the number of directions that glare calculations occur in. So the additional views you are looking for are only available if you use Radiance as your daylighting simulation engine.
