Add a surcharge to cart and checkout – uses fees API

add_action( 'woocommerce_cart_calculate_fees','woocommerce_custom_surcharge' );
function woocommerce_custom_surcharge() {
  global $woocommerce;

	if ( is_admin() && ! defined( 'DOING_AJAX' ) )
		return;

	$percentage = 0.0195;
	$totalCCExpense = ( $woocommerce->cart->cart_contents_total + $woocommerce->cart->shipping_total ) * $percentage;	
	$surcharge = ($totalCCExpense / 3) * 2; // They pay 2/3 of the handling fee, we pay 1/3.
	$woocommerce->cart->add_fee( '& Handling', round($surcharge, 2), true, '' );

}

The code above is what I did to add a handling charge to the orders. We have to manually do the orders, so I just add a small charge and have the customer pay 2/3 of that small fee, to recoup our loss of hiring the person to manually process orders. it does not cover it all, but helps us a tiny bit… But my question is…

I was able to successfully add a handling charge to the main order, but when it shows the future subscription order, it does not include the handling charge. How do I have it add it to both?

Here is the result of the cart when I added a product to it:

…
& Handling $1.02
Tax $6.33
Total $85.87
Recurring totals
Subtotal $62.32 / month
Shipping
UPS Ground: $16.20 / month
UPS Next Day Air: $67.54 / month
UPS 2nd Day Air: $31.41 / month
Tax $6.22 / month
Recurring total $84.74 / month
First renewal: August 7, 2023

See it did not add that to the Recurring Totals…

is there another function I can use to add it to the subscription part?
