Please include the marketing event Record ID as an available property to custom reporting! It is helpful to count how many unique events there are and using things like event name, start date or something else isn’t as reliable when you have multiple events on one day or with the same name.
Hey @ASidorakis 
thanks for the feedback. The next best stop for product feedback and suggestions is the Ideas Forum. Adding your comments there will help get it in front of the correct folks. Thanks! — Jaycee
Done!
Amazing! Thank you. There may be a delay before you see it live, just FYI. Have a great rest of your day! — Jaycee
