title: Laravels syncWithoutDetaching and additional data
body: <p>I have Googled my fingers sore, and I can't see anyone discussing this, but I have a suspicion that Laravels <code>syncWithoutDetaching()</code> method doesn't take any parameters for extra data like <code>save()</code>, <code>sync()</code> and <code>attach()</code> does?</p>
  
  <p>Does anybody know this? In the API documentation the method has the following parameters:</p>
  
  <p><code>array syncWithoutDetaching(Collection|Model|array $ids)</code></p>
  
  <p>I have trouble adding existing data to a relationship between a Guest and an Event. I need to add status for the guests and what event they are attending, maybe attending or declined.</p>
