title: Trigger build only if no changes on specified folder in Azure Pipelines
body: <p>I have a repo with two subfolders in Visual Studio Team Services: Code and Scripts. 
  I am now triggering one build (BuildScripts) when there's a change in the Scripts folder and another build (BuildCode) when there's a change in the Code folder using the Path Filters on the Triggers tab. If both folders have changed after a push or completed pull request then both builds will be triggered.</p>
  
  <p>What I'd like to do is trigger the BuildCode build if there are changes only in the Code folder. Is there a way to do this?</p>
