title: Query multiple insights metrics in one API call
body: <p>Is it possible to query more than one insights metric in one API call?</p>
  
  <p>For example to get the daily added likes for a page I executed the following call:</p>
  
  <p><a href="https://graph.facebook.com/_object_id_/insights/page_fan_adds_unique/day/" rel="noreferrer">https://graph.facebook.com/_object_id_/insights/page_fan_adds_unique/day/</a></p>
  
  <p>But I would like to have another metric, e.g., page_fan_removes_unique, included as well.</p>
  
  <p>Query the insights object entirely is a possibility, but gives me too much data I don't need, thus decreases performance.</p>
