Can I use Pathauto with additional url values?
The Sub-pathauto module is for exactly that purpose.


  The Drupal Path module matches only full URLs when creating SEO-friendly aliases. This module extends that behavior by also matching known sub-paths and replacing them with their respective alias.
  
  For example, if user/1 is aliased to users/admin, this module rewrites the link to the user contact page user/1/contact to use the aliased URL users/admin/contact instead. This also includes Views URLs taking a node as argument (e.g. node/%/yourview), in short, every URL that is based on, or extends, an existing alias. In combination with the Pathauto module it is possible to get rid of all remaining exposed internal non-administrative URLs.
