How to generate/pull a report from Appointments+ data

We are hoping to be able to reach out to customers around the anniversary of their appointment with us. Is there a way to pull a report from the booking data? We use Google Calendar to help track and double check bookings so if there is something that direction we are open to it! We currently use the follow up email code and it’s been great! I’m not sure if having a second version of that added but based on days rather than hours might work. Here is the link to what we are using https://premium.wpmudev.org/forums/topic/follow-up-email-after-appt-completed.

Details about us: We use the app for birthday party bookings. We would like to send an email a month prior to the anniversary of their previous booking date.

Thanks so much!
