I need to add the ability to sell packages or groups of tracks together on the site. I just want to add a link or menu item that says "packages" and then show a number of albums and when they click on the album I want to show the tracks for that album that can not be purchased individually but in a package. The extension is made to work like that. Selling albums and individual tracks. You can even set each track to be sold individually or as part of an album.
