Add subscribe to Mailchimp on user account creation

Hi there,

I manage an e-commerce where the user has to register first, and then he can shop only after account approval (using WP Approve User plugin).

Anyway, I’d like to know if it’s possible somehow to display the Woocommerce Mailchimp checkbox & text in the user registration form.

I’ve noticed that the form is displayed via the maybe_add_checkout_fields method, however I don’t know if it’s safe/possible to call it somehow outside the plugin (to not ‘hack’ it), as it would be better to stay within the functions.php file of our custom theme.

Have you ever thought to add this as a built in functionality in the plugin? It would be awesome to me.
