To add new values for how a customer can be related to a financial account, the administrator should add new values on the Role field of the Financial Account Role object. The Financial Account Role object is a junction object that links a contact or an individual to a financial account and defines their role or relationship with that account. The Role field is a picklist field that specifies the role of the contact or individual for the financial account, such as owner, beneficiary, trustee, or custodian. By adding new values on the Role field of the Financial Account Role object, the administrator can create new categories of financial account relationships for customers.
