Does field label change possible in the Promote and Change Position Redwood Page?

The business requires changing the field lable text on the Promote and Change Position Redwood Page.
We tried to make changes to the User Interface Text through the Sandbox, but we cannot find the text in the User Interface Text (Sandbox) to make the change.

Any idea how to achieve this change?

Path - MCG--> Workforce Structures --> Promote and Change Position

EX: Label text - What's the way to promote? - Marked in Yellow Color
