Can I create unique values for on_sent_ok and message?

Hi,

I want CF7 to generate a random unique ID for each form submission. Then, each ID has to be sent along with the message:

1. As a Google Analytics event, using on_sent_ok=”ga(‘send’,’event’,’Contact form’,’$unique-value‘);”
2. Send $unique-value in the message body.

Thanks!
