WooCommerce - Add custom fee to cart

gistfile1.php

<?php
/**
 * WooCommerce Extra Feature
 * --------------------------
 *
 * Add custom fee to cart automatically
 *
 */
function woo_add_cart_fee() {
 
  global $woocommerce;
	
  $woocommerce->cart->add_fee( __('Custom', 'woocommerce'), 5 );
	
}
add_action( 'woocommerce_cart_calculate_fees', 'woo_add_cart_fee' );

I got this working so that the fee is properly assessed and the customer pays the new total including the fee. I actually want to pass that fee on to the vendor. How would I go about adding that to the total they are able to withdraw?
