MarketPress: Shopping Cart & Order Status Pages Menu changes

Is there anyway to get the shopping cart and order status pages out of the default "store" tab and onto a secondary navigation? I know you can use the short code on a page which will provide a link, but I wondering if you can actually get the pages to appear on a tab, not a link.

I would like to have those two pages on the upper menu where the Order Status and Privacy Policy tabs are currently.
