Drupal 7 - Add two menu items with the same path but different query string
What I did is add the redirect module. 

Then I created custom redirects for those menu items, e.g. "node/add/alert/kind/regular" goes to "node/add/alert?kind=regular". 

No need for custom hook_menu programming. 
It worked! But why doesn't drupal provide it work out of the box???
