Custom fields allow you to configure linked fields. ## Feature Overview You can now specify the data source for each field imported into the directory. Choose from the employee master or connected SaaS services. This allows you to designate which fields are managed manually and which are synced from a master source. The trusted data source may differ per user. This feature lets you customize fields to fit your organization's needs. ## Feature Details * **Data Source for Directory Fields** When an employee master is configured, you can now set a data source for each directory field. The data source can be selected from the service (HRM) set as the employee master, or connected SaaS services. For services that can be set as the employee master, please refer to [supported cloud services](/en/it-management/tutorial/ikf8odm6ti-2#employee-master-supported-saas). * **Creating Custom Input Fields** You can now create fields (such as department) that can be linked to custom fields. For the list of available custom input fields, please refer to the [**Available Custom Input Fields**](#available-custom-fields) section. | Directory Field Data Source | Data Source Details | | --------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Directory field data source | - **This service**
