title: Add a query result (on any computed value) to a new WIT
body: <p>I am creating new WorkItemType and would like to populate parts of the WIT card in the board with computed values, examples include:</p>
  
  <ul>
  <li>Given a start date calculate the duration in weeks since then</li>
  <li>Count the number of fields that contain a valid value</li>
  </ul>
  
  <p>I am interested in either a way to include query results in the WIT card, or how to fill a defined field with computed values.</p>
  
  <p>EDIT: Running an on-prem installation of azure-dev ops and using the new process template with an inherited process</p>
