Select Status from orders screen

[Ciscowrig]

Currently, on the main orders screen in BO you can not select the order status.

I have found the code for when you select it inside the customers details, adminorders.php lines 453-464

/* Display state form */
       echo '
           <form action="'.$currentIndex.'&view;'.$this->table.'&token;='.$this->token.'" method="post" style="text-align:center;">
';
       $currentStateTab = $order->getCurrentStateFull($cookie->id_lang);
       foreach ($states AS $state)
           echo ''.stripslashes($state['name']).'';
       echo '

               <input type="hidden" name="id_order" value="'.$order->id.'" />
               <input type="submit" name="submitState" value="'.$this->l('Change').'" class="button" />
           </form>';

Where do I put that so the drop down and "change" buttons come up on the main orders tab? I can't find anything that relates to that table.

Thanks!
