Add On Options

I would like to create an automatic download file as a product and add on some options for discounted prints.

For example:
Digital file purchase $75

Options:
Add on discounted prints with your purchase

8x10 - $15
(2) 5x7 - $15
etc.

The problem I am running into is when I set up the options as a check list, they can only have the quantity of 1. For example if they want 3 8x10s added on, they would not have the option to do so.

Is there a way to set up quantities in the options area? If not, what would you recommend for this product?

The only way you would be able to accomplish something like that would be to create a collection that includes just 1 download product and add additional products ayt 0 quantity for them to purchase. Here is an article on how you would basically set it up.
