Trigger Condition for Review submitted/not submitted

I would love a condition to be added for when a review is submitted or not, so I could send guests a prompt to leave a review 3 days out, if for example they haven't left a review already.  Thanks!

I also think this would be very helpful. My goal is to send a private survey to guest ONLY after they have left a review OR after 14 days have passed automatically.
