Reusing completed DFFs in Journeys

Summary: Has anyone been able to request some information (e.g. Proposed Start Date) via a Configurable Form and then display the previously completed field (e.g. Start Date) to another user, like a Line Manager?

Content (required):

I have created a configurable form to request from the screening team a proposed start date following the completion of the candidate's background checks. I would like to then display this field populated by the screening team to the line manager to confirm as shown in screenshot below. I re-used the exact same configurable form to see if it was displayed populated but it is not, it is essentially a new form. Is there any way to manage this requirement? Many thanks for your input :)
