Hi,
Im using Appointment + and marketpress to provide bookable appointments. currently after a client purchase an appointment under provider it says "A Specialist" i need this to be changed to "Frances" see screenshot - http://monosnap.com/image/jXVryoCJVWptyyhM3bvjM7sAGBKCqP

They also receive an email stating the same thing that also needs changing ?
