Sorry. I'm mostly clueless regarding a Location field. It seems to allow you to tap a location on a map to approximate what the address might be, right? So, you can have an Address field that is slave to the Location field, but not the other way around, right? I haven't had much luck using them together.
This is from memory about something I've always wondered about, so if it doesn't make sense, please just disregard it. I'm sorry I can't help you more.
