Include no-show rate in reports

Each month, I report on the number of no-shows and our no-show rate. This helps our team understand how to adjust sign-ups to ensure needs are met. It would be great if this could be included as an option in reports - even if it was just the number of no-shows for each opportunity. Currently the only way I've found to track no-shows is to dig through the system log, which does not feel 100% accurate.
