composite position with a complex surface as the primary datum

composite position with a complex surface as the primary datum

I have a drawing that calls out for a composite of 8 diameters to ABC (PLTZF) AND AB (FRTZF) however my datum A is constructed of target points that do not form a perpendicular plane to any other datum. is this even possible to report in CMM manager? seems as though i need a plane in order to complete the reference frame.
