[phpOpenTracker-general] Page impressions and Top lists

Hi,

when I make a Top x pages seen pageimpressions are grouped by visitor_id
- meaning that several reloads from the same visitor is seen as one
impression.

When I get pageimpressions for a given document using:
phpOpenTracker::get(array('api_call' => 'page_impressions', 'range' =>
'current_week', 'constraints' => array('document' => 'pagename')))
every reload is counted.

Is there a way to get page_impressions to group by visitor_ids like top?

thanks.
