Self book - automatically save to EMIS if message opened/appt booked

Currently when sending a Self book message, when the patient opens the message or books an appointment both messages show in PATCHS as 'messaged opened' and need to be opened and manually saving to the clinical system. This is time consuming and I do not need to know if appt booked, can these just be saved to the clinical system? We will identify those that failed to book using clinical searches. Thank you.
