Capture custom field from woocommerce registration

Having a closer look at this, I have concluded that it is not currently possible. The only fields added to the mailchimp list are first_name and last_name.

However, the simple addition of a filter for the $merge_vars on line 114 of the class MailChimp_WooCommerce_User_Submit in file includes\processes\class-mailchimp-woocommerce-user-submit.php would allow developers to easily add extra custom fields to the mailchimp list captured in the registration process.

For example:
$merge_vars = apply_filters( ‘mailchimp_woocommerce_merge_vars’, $user, $merge_vars );

Please consider adding such a filter. I believe it would greatly enhance this useful plugin.

Actually,

$merge_vars = apply_filters( ‘mailchimp_woocommerce_merge_vars’, $merge_vars, $user );

would be a better order for the filter arguments.
