I am developing a site that handles content based on the domain name requested. Code in global.asax assigns a DeptID based on the domain. In using the scheduler, I only want to show/handle appointments for this DeptID. I think I need to treat this like a custom resource - but how do I implement that? I see how the documentation handles Rooms and Users, but I don't want to expose DeptID for the user to make a choice, and all appointments need to be filtered/inserted/updated for this DeptID only.
