I'd love to have the capabilities like Calendly where you can add a reconfirmation link (in the merge tags) so that we can see that someone has reconfirmed that they are attending and then have it show on the event (in event types section) that shows they have "Confirmed"
This has been so important for my process because I send out an email & sms a few hours before the scheduled time for the invitee to reconfirm and if they don't I'm able to reach out to them personally to either reschedule or get them to attend.
This helps so much to reduce no-shows and give peace of mind that the invitee has not forgotten or changed their mind about our meeting.
