Multiple Quantity boxex for add to cart


Is it possible to create multiple entry field option for product for “add to cart”?

For example: I am selling candy boxes which could be sold as individual box as well as in form of Case.

I want to display two text field something like below so that user can enter their numbers in appropriate boxes and click “Add to Cart”

For Example:

$9.99 per box: ________ quantity

$35 per case: _________ quantity

Please advice.

The multiple QTY fields isn’t possible without a code modification, but the Box / Case can be handled with a product option.
