lightbox exit popup

Hi, I am using this template to setup a pop up at the time of user exit: https://github.com/Adobe-Marketing-Cloud/target-experience-templates/tree/master/lightbox-exit-intent. It works great except I am not able to limit it once per session. Currently it shows on all pages when i hover over close button. I am ok limiting this once per visitor level too or even cookie. Is there a way to do that in target? I know there is one way where you can chose your reporting source as "Adobe Target" and you could go into the Advanced settings in the success metric and choose the option that increments the count and then bars from re-entry and set a  user to convert right away, like on user seeing **any mbox**. However I want to use A4T so I can do my reporting in analytics.

Please let me know if anyone has found a way to do this!
