Is it possible to have config groups other than 'site'?

[Max-Might]

Is it possible to have other config groups besides 'site'. In the example we have:

    'cgmconfigadmin' => array(
        'config_groups' => array(
            'site' => array(
                'mymod' => array('label' => 'My Module Options',  'sort' => -100),
            ),
        ),

Is it possible to have something like

    'cgmconfigadmin' => array(
        'config_groups' => array(
            'site' => array(
                'mymod' => array('label' => 'My Module Options',  'sort' => -100),
            ),
            'frontend' => array(
                'group1' => array('label' => 'My Frontend Options',  'sort' => -100),
            ),
             'backend' => array(
                'group2' => array('label' => 'My Backend Options',  'sort' => -100),
            ),
        ),

This would be useful when we have way too many options to show in a single page.
