this will take some custom coding to accomplish.
in the CMS Admin pane, create a new content area named "News", set it to be a template.
If you examine the power store webassist/plugins/cms_templates/news.php page you should be able to get a good idea how to display the news articles.
on that page, there is a recordset named "CMStoRS" using the following query:
SELECT C2.ContentGroup, C2.ContentPageSetOrder
FROM ps4_contents AS C1 LEFT OUTER JOIN ps4_contents AS C2 ON C2.ContentPagesetParentID = C1.ContentID
WHERE C1.ContentGroup = 'News' AND C2.ContentPageSetOrder IS NOT NULL
GROUP BY C2.ContentPageSetOrder
ORDER BY C2.ContentPageSetOrder DESC
this returns the news articles.
there is a repeat region to loop through the recordset and the cms code to display the news article header and content.
