Thanks, to customer support

I get regular "ticket closed" emails from one of the customer support systems we use here at work. The email includes a statement that says the issue was resolved or closed. It repeats the problem or request information that I entered, and it shows the resolution comments from the person who worked on the ticket.

There's just one thing missing--an option for me to say "thanks." Wouldn't it be nice if there was a URL in this type of email that would allow me to send a quick note to the tech who resolved my problem and say thanks?
