We don't have an option in the settings to add a repeat view to your tests, but it's very easy to add a new template with a WebPageTest script that logs the data for a repeat view. By making it a separate test, you can also benchmark them against each other and compare performance.
Here's an example script:
logData 0
navigate http://www.yourwebsite.com/
// Erase the current HTML to make the video easier to understand
exec document.body.innerHTML = "";
sleep 2
logData 1
navigate http://www.yourwebsite.com/
