CakePHP setFlash - Can it pass a variable to view?

Beneath is the code I'm using.  I'd like to offer the user the ability to restore the id of whatever it is they just deleted.  In order to do that I need to pass the id back to the view file:

	function admin_delete($id = null) {
		if ( !$id ) {
			$this->Session->setFlash('Invalid event', true);
			$this->redirect(array('action' => 'index'));
		}
		if ($this->Event->softDelete( $id )) {
			$this->Session->setFlash( 'Event deleted', true , array( 'restoreID' => $id ) );
			$this->redirect( array( 'action' => 'index' ) );
		}
	}
