I was super enlighten by the answer from user @Dennis Williamson, for solution to change the Style for all cross-references, which are usually applied in Auto-caption in Word Office, in a very neat and clean one time updating.

Steps described in link are very detailed and informative.

The main idea is to use find & replace method firstly show the source codes (by pressing Alt + F9) for all fields, then locate all cross-references by searching ^19 REF, finally update their styles.
