Only providers can have a schedule, so you need to create a provider to create a schedule.
To avoid actually giving the MA provider status, you could keep your MA with her current status and create a provider named, for example, "Schedule", with a password that only you would know. Use it to schedule, but nothing else (no messages, etc.).
It seems that there may be an unstated policy by AC to ignore "phantom" providers and not charge for them. These are providers like the one I just described who do not see patients, create notes, or prescribe. Hopefully this fair and generous approach by AC will continue.
