If a student wants to change their MPH option, they need to apply. It's an abbreviated application process, can occur at any time of year and is free. They will write a new statement of purpose and send it to the MPH administrative director, who will combine it with their original MPH application. She will send it to the program director for faculty consideration.

If a student wants to add a degree (concurrently), they will contact the department of the degree that they want to add to ask about the application process. If the student is already in the Graduate School (i.e. not a PharmD or DVM student), the process is often abbreviated.
