FoV offset for OAG sensors

The current FoV indicators for Starry Night and SkySafari Pro for guide cameras place the sensor center-of-mass of the imaging camera FoV. Would it be possible to allow users to add an offset (left, right, up down) to customize their FoV if using off-axis-guiders? This function could be useful during planning to see if guide stars will be available or not.
