title: how to set segment into angular 6 route?
body: <p>Issue:
  I want to set some segment after user login for ex. <code>http://localhost:4200/#/{dynamic name}/{dynamic name}/app/..</code>
   My problem is I navigate <code>/app/...</code> in across application.
  so I need to add all place this two segments before app.
  but I want to do global so no need to change in each and everywhere. it is possible?</p>
