Spatial references were never my strong suit, so sorry in advance if I use the wrong terminology somewhere 
I'm trying to use a custom geocoder to reverse geocode a geopoint via pulldata. Our custom geocoder is in state plane, but the default World Geocoder is not. What's the way to handle this?
Side notes: We are only collecting data within our jurisdiction, and would like to match the address entered to our address point. This is a public survey, and we don't feel that teaching users to select the proper locator in the geopoint question will make sense to many people.
