Step-by-step explanation:
To change a canceled consult in the VS GUI (Graphical User Interface), the best option would be to request a new consult through the system. This can be done by accessing the system and submitting a new request for consultation. Options such as contacting the clinic manager directly or using a third-party scheduling software may not be applicable or available in the VS GUI. Additionally, waiting for automatic rescheduling may not be ideal as it could result in a delay.
