Getting employee's private emails from HR module to Service

Summary:

Hi

We are using HCM and managing all employees' details using HR screens. Recently we've implemented HR Help desk based on Service. Only employee's work email is being imported from HR and this is the mail that the employee is being recognize when opening s SR using inbound email.

We would like that employee private email will be recognized as well so it probably should be synchronized into employee's record in service module.

Is there a way to populate employee's private emails from HR to Service module? I'm looking for periodic automatic process and not a manual way to export and import.
