Digital Download Attribute Set to Default? No more info link?

New Zenner here.

I've figured out that if you want to sell a digital download, you have to set up an attribute for that product. Subsequently, I discovered that if an item has attributes, instead of a quantity box and add selected items to cart button on the listing page, it will say "more info..."

Does anyone know a way to work around this? My client wants to be able to add multiple products to the cart at one time. So far it seems like that can't be achieved if a product has attributes, but I'm only using attributes for the digital download feature...

Thoughts? Thanks in advance!

If the digital downloads your customer wants to sell will be single-attribute products (only a download, no choice of file type), DrByte's posted a solution for you here.
