Add data to report

Hi How do I add more items under general, Tye seem to dom from a js structure called Data, how can I add to it?

I can mock the summary.htm and insert manually:

<div id="GeneralResults_Section">
 <h2><a href="#" onclick="ShowHide('GeneralResults')"><img id="GeneralResults_Img"/>General</a></h2>
 <div id="GeneralResults" class="section">
  <table>
   <tr><td class="generalCellTitle">Execution started:</td><td class="generalCellData" id="execStartTime">N/A</td><td class="generalCellTitle2">User:</td><td class="generalCellData" id="execUserName">N/A</td><td></td></tr>
   <tr><td>Execution stopped:</td><td class="generalCellData" id="execStopTime">N/A</td><td class="generalCellTitle2">Computer:</td><td class="generalCellData" id="execHostName">N/A</td><td></td></tr>
  </table>
 </div>
</div>

ddata taken from a data structure under <script>. 

But it would be nice if there was an array I could just push to.
