title: Is it possible to apply CLEAR_TOP flag for activity in manifest?
body: <p>I want to have an activity which clears top (clearTop=true) whenever there is an intent to start that activity. Right now I have to control the activity start from every place and manually add (xamarin.android syntax) activity flag to intent:</p>
  
  <pre><code>intent.AddFlags(ActivityFlags.ClearTop);
  </code></pre>
  
  <p>Please advise how to put this behavior into manifest/attribute</p>
