Rails 3 Routing

routes.rb

# Rails 2 routing
#
map.resource :city, :as => ":city" do |city|
  city.login 'login', :controller => 'cities', :action => 'login'
  city.resources :orders, :only => [ :show, :update ]
end

# city_login        /:city/login                      {:controller=>"cities", :action=>"login"}
#
# city_order GET    /:city/orders/:id(.:format)       {:controller=>"orders", :action=>"show"}
#            PUT    /:city/orders/:id(.:format)       {:controller=>"orders", :action=>"update"}


# Rails 3 Routes
#
resource :cities, :as => 'city', :path => ":city" do
  match 'login' => 'cities#login'
  resources :orders, :only => [ :show, :update ]
end

# login_city        /:city/login(.:format)            {:action=>"login", :controller=>"cities"}
#
# city_order GET    /:city/orders/:id(.:format)       {:action=>"show", :controller=>"orders"}
#            PUT    /:city/orders/:id(.:format)       {:action=>"update", :controller=>"orders"}


Note that in Rails 2 the login route helper is city_login_path(), whereas Rails 3 the 
generated helper is login_city_path(). But the nested order routes are both city_order_path()
 
Is there a way to make the single 'match' route consistent with the resources in Rails 3?
