Update DFF value in Process Requisitions

Summary:

Sometimes it takes some time for the buyers assess and decide on Purchasing Strategy, to to market or not. And while these investigations are ongoing, we would like that the buyers or the Procurement Manager to be able to separate which requisition lines are ongoing investigations and which are new.

Used the page composer and was able to make a DFF segment editable in the table layout. But unfortunately I have not been able to figure out how to save the update. Is there any way this can be done?

If not, do you have any other workaround? (in addition to creating dummy buyer / worker records which would be the last resort)
