title: Is it possible to query when a specific field changed in Azure DevOps?
body: <p>I have a DateTime field (MyDTField) in my Azure DevOps instance (I am an admin on it, so I can change its schema if necessary). I would like to write a query that returns any items where the above field (MyDTField) changed in the last 7 days. Is this possible to do?</p>
  <p>For e.g. the built in &quot;Changed Date&quot; field allows us to write a similar query, but that returns work times where any field value changed. I want to get items where a specific field changed within a specified time period.</p>
  <p>Thanks!</p>
