Addresses upload employee city in HDL is it possible by code and not city name?

Hello ,

We would like to upload addresses to employees by city CODE and not name.

The main issue in addresses is the City of the Employee.

Issues is - so far we used In the HDL file , the city name of the employee.

This causes issues since when changing in the “manage geographies ” the city name - it doesn’t reflect the existing addresses of the employees.

is it possible to upload the city in the employees addresses HDL file as a CODE and not city name ? If so how to implement thAt ?

Also - how can we validate the city provided during the HDL upload
