Allow a staff to set his/her default department
We are required to choose a "current desk/department" for each login. However, since each staff usually has his/her major role, meaning he/she might most of the time work on the same desk/department. To be more friendly, it's better to have staff to set his/her own default department and select other location when necessary.

As a workaround, you should be able to deactivate the forced choice
"Otherwise, the system will automatically set the physical location to the user’s last specified location."
