Currently, there is no way to add guests after a scheduling request has already been scheduled. If an additional attendee needs to be included, the only workaround is to cancel the existing request/appointment and create/send a new scheduling request with the updated guest list.

This creates extra administrative work and can cause confusion for clients or internal team members, especially if the original scheduling request has already been received, viewed, or partially acted on. It also increases the chance of duplicate communication, missed scheduling responses, or delays in getting the meeting booked.

It would be very helpful to have the ability to edit an active scheduling request and add additional guests without having to cancel and recreate the request. Ideally, the added guest would receive the same scheduling request while the original request remains active for the existing recipients.
