cnMaestro Guest Access Portal confirmation email

Would it be possible to send a confirmation email to clients who purchase time through the PayPal portal? I see that the token is added to the field on the confirmation page when PayPal redirects the client back to the browser–but, in my experience with clients, they are often password-challenged and either ignore or forget to write down their token. At least this way they would have a digital copy of their token and would reduce the number of trouble tickets we receive. Clients do receive a confirm email from PayPal, but it doesn’t include the token, obviously. Thanks!
