title: Is there a way to register routes after the application is started?
body: <p>I want to have app which has some default route and controller (Let's say Login page). I can register this at the <code>Configure</code> method but after the user successfully logs in I want to fetch the pages related to the user and register them so he can have access to it. Is there a way to achieve that?</p>
  
  <p>As long as I read that's impossible but who knows, I'm new to <code>ASP NET Core</code>?</p>
