title: EmberJS Set Multiple Properties At Once
body: <p>I am setting lots of properties with a series of set calls e.g.</p>
  
  <pre><code>this.set('prop1', value1);
  this.set('prop2', value2);
  .......
  </code></pre>
  
  <p>Is there a way to do this in one call (similar to when I create an object)? E.g.</p>
  
  <pre><code>this.setMultiple({prop1: value1, prop2: value2});
  </code></pre>
  
  <p>I still don't fully grok Ember's inheritance model. Maybe something along the lines of <code>reopen</code>?</p>
