Exclude pages in one page list from pages in another page list

Permalink
I have a page list with 4 featured pages ("Top News") and another page list with more non-featured pages ("Latest News").

The "Top News" page list has no pagination. Therefore, I need to display top news which are not currently visible, in the "Latest News" page list.

My "Top News" page list looks like this:
$pn = $c->getCollectionHandle();
$home_featured = new \Concrete\Core\Page\PageList();
$home_featured->setItemsPerPage(4);
$home_featured->sortByPublicDateDescending();
   $home_featured->filterByAttribute("is_featured",1);
if ($pn != 'home')
   $home_featured->filterByParentID($c->getCollectionID());
$pages = $home_featured->getPagination();
if ($pages->getTotalResults() <= 4 || $pn != home)
   $pages->setCurrentPage(1);
else
   $pages->setCurrentPage(2);
$pages = $pages->getCurrentPageResults();


My "Latest News" page list looks like this:
$pn = $c->getCollectionHandle();
$news_list = new \Concrete\Core\Page\PageList();
$news_list->setItemsPerPage(6);
$news_list->sortByPublicDateDescending();
$news_list->filterByCollectionTypeHandle(array("article"));
if ($pn != 'home') 
   $news_list->filterByParentID($c->getCollectionID());
else
   $news_list->filterByAttribute("is_featured",0);
$pagination = $news_list->getPagination();
$current_page_num = $this->controller->get('ccm_paging_p',1);
$pagination->setMaxPerPage(6)->setCurrentPage($current_page_num);
$pages = $pagination->getCurrentPageResults();
$totalPages = $pagination->getTotalPages();
