More Options to Edit Class Manager

I would like more options to edit the access teachers have in class manager. For example, with our studio size and the limitations of the appointments and private lessons feature, we need to run all appointments through our office staff in order to ensure studio availability. I would like to remove the option for teachers to book/cancel their own lessons. Not remove it for everyone in Class Manager, but to have the ability for us to customize for our own studio what teachers have access to and what they do not. The current customization is somewhat limited.
