Custom Header Single Page

Two part question…
—————————————————————————-
I would like to create a unique header for single page on site. More specifically I have been provided by plugin vendor a php shortcode (<?php wd_slider(2); ?>) for a banner I would like to substitute for default header banner image.
—————————————————————————-
Here is what I have tried…

1) Create template page.
2) Added existing header.

Here is that template page…

<?php /*
Template Name: Aerial Page Template
*/
?>
<?php get_header(); ?>
<?php get_footer(); ?>

My questions are:

1) Where in the header.php should I substitute ‘<?php wd_slider(2); ?>’
(shortcode provided by vendor) and save to new header2.php file.

2) In the template code (above) instead of <?php get_header(); ?>, how do I refer to the newly saved header2.php?

… or is this even the right approach?

Thanks in advance,

Noah
