If I understand your question, maybe you just need to do some initialization when the object is created. Look at NSManagedObject:awakeFromInsert. It's where you can do initialization (conditional if you wish, as long as you don't do something to disrupt the "insertion" process). It's perfectly legal to populate relationships there too (ie: maybe every "Player" needs an array of "Things" when they're er..... hatched).
