Create the option to schedule a recurring appointment that happens multiple times a month (2nd and 4th Wednesdays) in a single appointment.

Right now, in order to create this kind of schedule I need to create 2 appointments, one that repeats on the 2nd Wednesday (for example) and another that repeats on the the 4th Wednesday. This causes problems when the overall schedule changes or if there are details to be added to the appointment in that now those changes need to be made twice.
