Redirecting old path alias to new one ?

I use Pathauto & Global Redirect in Drupal 7.12.

When i change the title of node, path of node changes automatically by pathauto.

But both old alias and new alias have http 200 code.
Is it possible to Global Redirect make a 301 from old alias to new alias?

(I know that "redirect" module does that, if you manually change alias. if pathauto changes alias no 301 is created)
