$this->Session->setFlash();

I was wondering is there a way to add a class to the session from the controller?

 

The setflash as far as i can see is used for alerting user after a save attempt so

 

$this->Session->setFlash(__('Information Updated.', true));

 

or

 

$this->Session->setFlash(__('Error! Please try again.', true));

 

So the idea would be for the success message add a class so the message text is green if failed text is red.

 

Any way this can be done?
