Non-member Membership - Fees

We require an additional $10 for non members whenever they use our facility. The guest (non member) fee is fixed but the court fee is hourly. Other than adding the additional $10 manually to non member court costs every time they reserve a court, there is not an automatic way to do this. It would be nice if in the membership court cost we could create the hourly court rate and have an additional fixed rate for specific membership types.
