Is it possible to enable automatic numbering in a Descriptive Flexfield (DFF) in Oracle Fusion?

Summary:

We would like to enable automatic numbering in a Descriptive Flexfield (DFF) on the Employment page in Oracle Fusion HCM. Our goal is to assign an additional unique sequence number to each employee, separate from the standard Employee Number. This sequence should be system-generated automatically upon employee creation, without requiring or allowing manual entry.
