I need to be able to GET and PUT Address custom metafields using ServiceApi. Currently this is possible for Organization business entities using the json body "Properties" array. This is documented in the API documentation. But if a custom metafield is added to an Address, which is used on an Organization with the "Addresses" array, neither can you GET the custom metafields in the response, but neither can you PUT the custom metafields in an update.

I was informed that this was indeed not possible right now in ServiceApi hence my request here to have this added.
