Edit wordpress theme Featured News to show Manual Selection

Hi I have a Featured News Box at the Top center of my page. If you enter the website you will see it. It is currently displaying the most Recent post of 3 categories that I select. I want to change that by being able to select 3 - 10 news that I manually choose to feature (by having a check box to select the news I want) and it will rotate between the 3 tabs the 3 - 10 manually selected news. Bid if you can do it. Thank you Please see link for a demo of the site: [login to view URL] Please PM me if you are unsure what I want.
