You can add it directly through your functions.php, unfortunately this is not documented very well at all.

You want to hook into add_comment_meta using add_action, to look at this further refer to line 500-ish of comment.php.

It looks like this

function add_comment_meta($comment_id, $meta_key, $meta_value, $unique = false) {

    return add_metadata('comment', $comment_id, $meta_key, $meta_value, $unique);

}
