In Work Skills conditions, we are able to add conditions for native fields [czip] and [cstate], however native fields [cname] and [ccity] are not available. All 4 fields seem to be setup in the same way. Is there a way to add work skill conditions for [cname] and [ccity] without having to resort to message steps to copy those native fields to customer properties?
