Total points when using categories

The views bundled with User Points show Highest Users only per category. If you choose All categories in the exposed filter, it will show the user more than once. So, for example, if user1 has 1000 uncategorized points and user2 has 700 uncategorized points plus 500 points in category X, the view will show user1 (1000 points) above user2, when actually user2 should appear first, as he has more points (1200 points total). And user2 will appear twice once in the list, one for each category, which is confusing.

Is there a way to create a view that shows and sorts by total points?

Thanks
