You can have one or multiple columns in the calendar which can contain appointments that can be used by multiple users or multiple teams. See the instructions below for how to create a column in the calendar to use for booking appointments for more than one user. You can do this in two different ways.
Add a Column for a Resource
Add a resource called, for example, 'Emergency'.
Schedule bookable shifts for the resource. The 'Emergency' list/column appears in your calendar and you can book appointments without needing to add a responsible staff member.
Note
When checking in the appointment, remember to change the person responsible for the consultation.
Add a Column for a Virtual User
In Settings > Users, create a user called, for example, 'Nurse Appointments', and select the Virtual user checkbox. This tells the system that the user is not a real person.
Go to Calendar > Shifts and schedule bookable shifts for the virtual user. The 'Nurse Appointments' column/list will appear in your calendar.
The advantage of having a virtual user as a column is that multiple users can subscribe to tasks for this user, which helps with internal communication.
