Making Mapped fields from transferred Vacancy Requests editable when creating New Position Opening in A-Recruit

I have been told that mapped fields from a transferred vacancy request from SHR, are NOT editable in A-Recruit when crating a New Position Opening from the linked Requisition. Fields are either hard coded form the sent information form SHR, or free texted in A-R.

Example... The Salary field we would like to be able to edit if needs be, when creating the Position Opening if there have been a change/or correction needing to be made since the vacancy request has come through from SHR to A-R.

Because this currently cannot be made an editable field when creating the position opening from the Requisition of the transferred vacancy request, it is now seen as a free text field in the position opening workflow. Which means in the scenarios whereby the salary has been sent correctly, it wont be seen on the create position opening workflow, thus making it redundant to even send the data through.

Recap - it would be great if any data/fields that is sent through from SHR Vacancy Requests, can then be edited and not hard coded when creating a New Position Opening from the linked Requisition in A-Recruit.
