Sending files with Invoices

[cyberrick]

Whenever someone orders from the website I want a digital file to automatically be sent along with the invoice.  Can someone tell me if there is a way to do that within Virtuemart?

Using, VM 3.2.12, Joomla 3.8.3

Site is http://daypunch.mtnwestdev.com/index.php

If it is the same file for all products you can use the General mail attachment option in VM Configuration/Emails
