title: Add dynamic route in Symfony1.4
body: <p>I'd like to know, if possible, if I can add/register a new route dynamically, based on some paremeter.</p>
  
  <p>I know that a route is somethig like</p>
  
  <pre class="lang-yaml prettyprint-override"><code>newsdetail:
      url: /newsdetail/:id/:title
      class: sfDoctrineRoute
      options: { model: News, type object }
      param: { module: articles, action: articledetail }
      requirements: 
          id: \d+
          sf_method: [get]
  </code></pre>
  
  <p>But now, is there a way for me to add, or prepend this kind of route in an action?
  My problem is that the module and the action could change depending of the site instance...</p>
  
  <p>So, I've built a component that do something and two different modules, suppose module1 and module2, both two including the component. 
  For different reasons, I can't register in the routing file all these routes.
  Now, the user1 have to have the route that go to module1, and the user2 have to have the route for the module2.
  So, I'd like to add the route in an action.
  I hope I have explained it better</p>
