If what you mean is having a topnav & a side nav only displaying items (all children, grandkids, greatgrands, etc)for the section you’re in, yes. Here’s what works for me:
$ancestor=current(_wswwpx_page_get_ancestor_ids($post->ID));
$args=”title_li=&sort_column=menu_order&child_of=”.$ancestor.”&depth=0″;
wp_list_pages($args);
