Fast steering mirror angular resolution

I am trying to model the use of two fast steering mirrors in my system. I am currently modeling their adjustments by performing a local optimization that centers the beam on the image plane by tilting each mirror. I want to add the angular resolution from the physical system we have purchased. I have limited the tilt parameters for the maximum tilt, but I want to also limit the resolution of the mirrors. Is there a way to do this using the MFE? Thanks in advance.

Sounds more like a ZPL macro solve in the MFE.  The angles would be optimized as continuous variables, but then changed to the nearest angle possible using something like INTE(angle*resolution+0.5)/resolution, where "resolution" is the finest possible angle the servos or steppers can provide.
