Override file for display of paypal payment type "Shopping Cart"?

[aerdna]

I'm running VM 3.0.16, Joomla 3.6.2, PHP 5.6

I would like to use the PayPal "payment type" of "Shopping Cart" so that the actual items in the shopper's cart appear on their PayPal checkout page. I'm using PayPal Standard.

I can't seem to find where I would override the Shopping Cart contents that get sent to paypal.  One of my manufacturers does not allow showing their SKUs to the end user, but I need these in the backend.  The info that gets sent to paypal includes by default the product name and the manufacturer's SKU.  I've made overrides to omit the SKU from the front-end, invoices and emails but can't find where to override this for paypal.  Yes, I could just use the "Normal" payment type but I really would like to show the breakdown of each item.

Is there an override file I can create or is it somewhere within the paypal plugin itself? 

Thanks,
Andrea

I found it! 

Saw an older post from GJC Web Design on some paypal stuff which refers to this file for modifying prices:
