Zend_Form_Element_MultiSelect element definition

Is there any way to define which options in Zend_Form_Element_MultiSelect would be selected by default?

  $element = new Zend_Form_Element_MultiCheckbox('foo', array(
      'multiOptions' => array(
          'foo' => 'Foo Option',
          'bar' => 'Bar Option',
          'baz' => 'Baz Option',
          'bat' => 'Bat Option',
    );
  ));
  $element->setValue(array('bar', 'bat'));
