Clone of simplenews node that has been sent

When you clone a simplenews node that has been sent (emailed), the clone node also has the status of being sent and so it cannot be sent again. I have a client who wanted to able to clone a newsletter so it could be sent to different newsletter groups. To solve this problem I have written a small custom module that resets the status and count of emails sent, could this be included as a feature in a future release

extract of code...

function module_form_alter(&$form, &$form_state, $form_id) {

  switch ($form_id) {
	
  case 'simplenews_node_form':
  
     if (stripos($form['#action'],"/clone") !== false) {
	
        $pnode = $form['#parameters'][2];
        $pnode->simplenews['sent_subscriber_count']=0;
        $pnode->simplenews['s_status']=0;
        $form['#parameters'][2]=$pnode;
		
        $node = $form['#node'];
        $node->simplenews['sent_subscriber_count']=0;
        $node->simplenews['s_status']=0;
        $form['#node']=$node;
     }
    break;
	
  default:
       break;
	
 }//switch

} //module_form_alter
