Multiple instances of same object using Restkit Object mapping

I'm using Restkit object mapping with the nested json data below. It will works great and each song object has a relevant rapper object. Except as you see below the rapper is the same for both songs, but each song object has a separate instance of a rapper object, so they don't match up when comparing. Is there a way to have Restkit use the same instances if they exist based on the unique id?

{
            "id": "1",
            "user_id": "200",
            "filename": "filename1.mp3",
            "mdate": "1250191261"
            "rapper": {
                "name": "Rap King",
                "id": "200"
            }
        },
        {
            "id": "2",
            "user_id": "200",
            "filename": "filename2.mp3",
            "mdate": "1345630910",
            "rapper": {
                "name": "Rap King",
                "id": "200"
            }
        }

If you are using a Core Data backed mapping you need to set primaryKeyAttribute=@"id" on your RKManagedObjectMapping.
