Updating OOTB Service Request Types in Service Catalog.

We are looking to add the functionality of editing the Menu Title for Out-Of-The-Box service request types in the Service Catalog e.g. SERVICE DESK - INDIVIDUAL MOVE, SERVICE DESK - HOTELING.

Currently, the Service Catalog is where all the request types in Workplace are created. It shows the Out-Of-The-Box request types and allows you to update the Menu Titles, but changes to the Menu Titles or descriptions are not reflected in the corresponding work request tiles in Workplace.

You are also given a manage activity types task, to edit the same Activity Types/Service Request types. It also does not allow you to update the activity types, which is where the help guide suggests you make edits to these items.
