MedWare is the name of a Sage product which means the support is assured by the Sage corporation. You will need to get in contact with them to be able to get support about online scheduling. Yes, there is online scheduling, but before doing that, contact the developer to obtain additional information.
These Sage products are not for the regular user. They're meant for the companies and multiple corporations. I've recommended to contact them because this seems to be the simplest method of getting help with your request.
