We have certain estheticians who do not perform certain services, but even if they are non assignable in the system reception is still able to book the service in. I know a message pops up that says "This person does not usually perform this service:" , but if you miss that they are still able to book it. The older system we used did not even allow us to move it over and only allowed estheticians who performed the service take the service. A way to have it not even be able to be booked on out end to make sure there is no mistakes on peoples books would be great. Again, I know we are able to do non assignable and assignable and we get a message that says it, but something more would be great.
