489657 Change Product Display In CMS Shop Builder from A-Z

We are looking to have someone modify the CMS Shop Builder component on the following websites: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] Basically we need some way in the backend to control the order in which the products are displayed. For example we would like to display the products according to the first two letters in the product code (sku) so if I wanted to show all the products thats sku's started with TR I could and then I could specify all the product sku's starting with MD will be 2nd and so on. Please contact me if you require any further info.
