I'm adding in a delivery date and time to the checkout process, and need to change modules/pages/checkout_shipping.php.

Can this be overridden with a template? or do I just have to replace the file?


If a template override works for this one, where do I put it? normally there is a 'classic' directory to indicate where overrides can be placed, but not in this case, so I am assuming it's backup followed by change (followed probably by tears before bedtime!)

thanks
