Link to tabbed view?

I'd like to use taxonomy menus to link into a page of Ubercart catalog items, with different kinds of items separated by tabs. The Custom path option in taxonomy menu seems to require that it end in with the views argument (%), and I can't figure out a way to make a tabbed view that will appear at the end of a path that ends with an argument (Views has thrown an error saying a tabbed View can't end in an argument).

So--taxonomy menu lets me use a path like this: categories/%
But to land on a tabbed view, Views requires a path like this: categories/%/all

I've thought about using mod_rewrite (Apache) to append the '/all' to any path that ends with 'categories/[0-9]+' -- e.g.:

RewriteEngine on
RewriteRule ^(categories/[0-9])$ $1/all [L]

but (using the Acquia Drupal stack), can't get it working. (Not a lot of experience with mod_rewrite, so good chance I'm missing something.)

Does anyone know of a way to accomplish this? (Preferably the application -- e.g., Taxonomy Menu or another Drupal module.)

Thanks
