Yes, there is. In order to control which items are displayed in your scrolling gallery, please click the "Store Items" link under the "Store" tab within your account. Any items that you designate as "Featured", assuming that no more than 14 items are assigned that status, will always be displayed in your scrolling gallery. Similarly, any listings you designate as "Hidden" will not be displayed in your Auctiva store or scrolling gallery.
