When you go into the calendar you can add new staff. Try adding staff to the calendar then add them to the service before removing the previous member. https://outlook.office.com/bookings/staff
The services don't have their own categories, sorry. But if the staff members are only assigned to one service, you could use the staff category colors for uniformity - give them all one color.
