How to turn on "Improved Dimension Labels in User Interface" in RPASCE?

Hi all,
The environment I am working on:

RPASCE Client (JET UI)	RPASCE.25.1.102.0.5.0125.1.202502272308.1650423.232
RPASCE Server	25.1.102.1.2.2784
Application Config (mfpscs)	25.1.102.1.2.2526

In RAP Advance Release Notification for 25.1.101.0, there is a section introducing a new feature to display concatenated position ID and label in user interface.

Improved Dimension Labels in User Interface
Customers can now opt to have position IDs prefixed to dimension labels by setting the preferred option through PDS Properties. This allows the customers to choose the hierarchies where they want to see the position ID and label concatenated. This concatenation of ID and label allows the user to distinguish items with the same label from each other.———————————————————————————————————————
