Need to Improve MP3 Download Feature

[ultra1bob]

I've started making MP3s available for sale. I'd like to easily make a class available that would have maybe 20 download files.
Right now, there's no easy way to do this. I'm using a dropdown menu listing the classes by number, but I apparently have to list the first class as the main title in Shopsite before adding the others.

MP3 downloads are now common for purchase. Please try to have a better system. Thanks.
