title: IPP Customer Query Issue - SyncManager updates timestamp even though no changes made
body: <p>Is there a workaround for this case?</p>
  
  <ol>
  <li>I programmatically modify a customer in the cloud.  </li>
  <li>SyncManager pulls that customer down to QuickBooks.  </li>
  <li>I subsequently query for modified customers and get that same customer back since SyncManager updates the timestamp even though no real changes occurred in QuickBooks.</li>
  </ol>
  
  <p>I need a StartCreatedTMS equivalent for list items so that I will only pull entities that were physically modified in QuickBooks.  </p>
  
  <p>I've attempted to insert the StartCreatedTMS tag into the query but they are ignored, ostensibly because they were designed for transactions.</p>
  
  <p>Any ideas?  </p>
