@CityofColumbusDepartmentofTech , unfortunately there is no setting to return the UnitName or SubAdr fields that show up in findAddressCanddates requests in reverseGeocode requests or to have it included in the 'Address' output field. From a reference data security standpoint, someone could use reverseGeocode requests to reverse engineer your reference data.
One workaround to consider involves some data manipulation, but you could use Calculate Field to populate the 'Address' field in the geocode result with the value from the Match_addr or LongLabel field.
Out of curiosity, what is COTS?
You could submit an idea for this or an enhancement through TechSupport.
