Since the masks applied to motion sensing actions are bascially just x,y coordinates, why can't we define them for each PTZ preset?

Use Case:  during the day, my PTZ camera monitors an area that people have access to, but should not be crossing and into another area. Motion/people capture zone is well defined.  At night, it points at a completely different spot that is a potential egress spot for tresspassers. A completely different zone with different motion areas.

Use Case:  patroll mode. When in spot 1, watch for motion in area X, when in spot 2, watch for motion in area Y
