I have an issue with the memberships:

We have a leveling system with estheticians where they can level up and their price goes up. Our memberships include levels 1-3 staff for the monthly price but if they pay additional $20, they can book with an advanced esthetician. Right now, we have to add an upgrade fee at checkout, but it isn't clear to the client when booking their appointment which service provider is included and which is not. Our advanced estheticians are not on online booking right now, would love the option to put them up online for the membership facials and have the client clearly see when booking that they will have to pay additional $20 when booking.
