Booking multiple treatments in one booking

It should be possible to book multiple treatments/services for clients for one clinic visit
E.g if a client comes for laser hair removal underarms and also wants a hydrafacial, I should be able to book these both in without it being a seperate booking with a seperate email and text confirmation. There should be one text confirmation, one email with all services listed on it and this would really help my clinic as people always book multiple treatments in one session eg underarms laser, hydrafacial and dermal filler consultation.
Also, it saves me the user money in unnecessary sms and saves the client the annoyance of getting 3, 4 or 5 SMSs and emails.
Please fix this or provide an option to accommodate this for those clinics who wish to stack their services in this way
