Multiple files for virtual downloadable products

[munimkazia]

I am planning to use prestashop for an online music store. The music store will contain albums as downloadable products. But, for each product, I want the customer to be able to download each song individually, and in any format he wishes (we are planning to give out MP3s and FLACs).

Prestashop explicitly allows only one download file per product.

Has anyone here managed to modify the code to allow multiple download files for one product?

I have started looking at the code and hacking it, but if someone has already did this, it will help me a lot.
