Hello Rabsun,

Thank you for reaching out to us.

When you go to the edit employee section and create a special day, you also have the option to add in which location that employeewill work that day.

The location of the service depends on the location of the employee.
In case you have more employees on that service who work in different locations, customers will have to choose a location.

You can either unassigne the rest of the employees for that day or you can create special days for all of them and set that they are working on that location.

Hope this helps.
