title: Display additional dialog when application is in upgrade mode
body: <p>I created a setup file which is working awesome.</p>
  
  <p>Now whenever I rebuild an application without changing anything but Package Code is changed and then while I am going to install this version then a dialog will come "Upgrade Dialog" which ask me for upgrade an application.</p>
  
  <p>Now in this situation I want to display an additional dialog created by me.</p>
