Changing People Picker scope (for resolving entities) in SharePoint 2007

Question

I've a custom application page test.aspx. I've a people picker in test.aspx.

I open the page with the url http://site01/_layouts/test.aspx and I want the people picker to resolve the SharePoint groups in the site http://site02.

By default the people picker resolves the entities belonging to the current site collection. How can I change the scope to a different site collection?

I guess it can't be done. All I'm getting when researching about people picker scope is this - http://www.sharepointblues.com/2010/08/30/limiting-people-picker-scope-in-sharepoint/.
