title: Change title dynamically for MvcSiteMap?

So is it possible to change <code>Title</code> dynamically. Only change is Edit address will have parameter value <code>AddressID</code>. How to change title dynamically?</p>
  
  <pre><code>[HttpGet]
  [MvcSiteMapNode(Title = "Add Address", ParentKey = "Addresses", Key = "AddAddress")]
  public ActionResult GetEditAddress(string AddressID)
  {
  </code></pre>
