latest activity in river dashboard layout

Hi Guys,

Any idea how I can get the latest activites but displaying them in the riverdashboard list layout?

I am currently using:

    $activity = list_registered_entities(0,25,true,false,array('object','group'));
    set_context('latest');
    $activity = elgg_view_layout('', '', $title . $activity);

But I would prefer the listing shown in the riverdashboard.  Any ideas what I need to change would be great.

Thanks
