When you add a new person to Services with Viewer permissions or higher, you can start them off in a specific folder. This is helpful if your account has many folders or sub-folders, and it's difficult to find the right one.
To set a Home folder for another person, you must have Scheduler permissions or higher.
To set a person's Home folder, go to the Details tab in their profile, and then choose a Home folder from the dropdown.
When that person goes to the main plans page next, they will be in the Home Folder that you set without having to navigate there themselves.
