OsCommerce "Order History Box"

I have an OsCommerce store and I only sell “downloadable” products. My project is quite easy to explain: 1.  In column left , ”Order History” box, the links now transfer the client to account_history_info.php. I want the links to instead be links directly to the downloadable product. 2. I have installed contribution ”Super Download Shop” so that I can add multiple files to one product in admin “product attribute”. In order history box I don’t want links to to all of theese files to show. I only want one link to show – a link to the “main file” and I want to be able to control what file to be the “main file” from for example “product attribute”. Please get back to me with your thoughts on how to solve this and we can get started immediately, Carl
