Ability for a service to be seen in the service list but not actually be booked
For example, packages where you can get a facial with an esthetician and a massage with a massage therapist done on the same day for a discount. There's no way to book this package properly online. It would be nice to have the option to have it list online so clients can know it's an option without being able to actually book it. Right now you can leave it listed with a note to call to book but they can still book it themselves if they want to. That results in scheduling messes. Or to leave it off the online options, but then they don't know that those services are available.
