title: Core Data Fetched Properties
body: <p>Though I have been using Core Data for a while now and in a number of apps, I have never yet used Fetched Properties.</p>
  
  <p>In my current project I have an entity with relationships in the Default store, this same entity is also in the Second store.
  But in the Second store I want to have some of the relationships changed to Fetched Properties.
  Is that possible?</p>
