Amazon S3 - How to use MarketPress to download a Folder with Multiple Files

Trying to do a digital download using MarketPress, using Amazon S3 for the file transfer service.

It is a Folder with the 4 CDs / 4 Files.

Anyone know how I can link 4 links or how I would use an S3 Folder with the 1 URL in MarketPress for a Digital Download?
