Allow us to input service assignments
Currently, you can specify subject area assignments for each tutor, but not assign tutors to services. This means that every schedule block for every tutor needs to be set manually when adding the schedule. This is time consuming and creates the probability that mistakes will be make, and students will end up booking appointments with tutors who can't help them. We should be able to specify service assignments for tutors, or at least specify a default when they create new schedule blocks, rather than it defaulting to all services.
