Allow Discounts --> Reservations to be applicable to only certain types of Reservation Types.

Currently, all the Reservations Discounts applied to memberships are for ALL reservations. As an admin, I cannot specify certain reservation types that they apply to. As a larger facility with tennis, pickleball, golf, etc. this means that I cannot do a "Tennis Only Membership" or "Pickleball Only Membership" that allows those members to get free court rentals for those specific types of courts or reservation types.
