adding a phone field in out of stock form of commerce stock notifications drupal commerce

Question

Is there a way adding a phone number field (along with the e-mail) in the out-of-stock form that is being used from the commerce stock 7.x-2.2 module and commerce stock notifications 7.x-1.1 module?

I am using drupal commerce kickstart2 and when i have a product that is out of stock the above modules helps no to be able to add them in the shopping cart as long as it gives the option to fill in an e-mail address. I would like to add a phone number field as well under the e-mail address I was wondering if anyone knows how.

Ash joshmiller noted, you can add a field using a form alter and then add another custom submit handler to take the submitted values and do something with that data. You'll have to provide your own DB or come up with some method to store that data on the customer or product.
