Woocommerce - Add Product Attribute and Radio Buttons

Greetings,

For one of our woocommerce websites we need to make small updates to one category of products. There are four (4) products in the category that will need the following:

1. Add a new product attribute with two possible values
2. Make the product attribute selectable on the front-end with radio buttons
3. Rebuild the product variations for the products with the new attribute added
4. Adjust front-end CSS based as needed to make it look great on all browsers / screen sizes
5. Test and Verify all is working correctly

Attached is a screenshot showing the current attribute options and a mockup of the desired update.

Thanks,
Benjamin
