Drupal path prefix based node content
What you want, is not (simple) with only views and CCK. That is because both lack a system for persistence in filters and arguments. 

I can advise you to add a new module to your stack: Domain Access. This is a large module, which is not simple to configure right, but it sounds like it is the exact solution to your problem. It will allow you filter content, based on the domain (franchise) it is posted into.

The mayor concern with this module is its complexity. The second concern would be its use of Drupal's content access hooks and system. Modules like Domain Access, i18n, Organic Groups all use this system, which has very severe penalties for performance. IOW: Domain Access, or any access-module, will make your site notably slower and less performant.
