Unfortunately, sections can not be added to tabs via the drag and drop.
However, you could add the sections to your page and then using Firebug or Chrome/Safari's web dev tool, inspect the HTML code and then add this to the tabs shortcode that was added in 2.2. Once you have completed this, simply drag and drop the banner/boxes section to the inactive area.
You could also contact one of the PageLines Pro's and see if they're able to assist you.
