Manage Requisitions - can Order field be used to auto-fill the Supplier field on the Search function

Summary: We have a user who believes that when our organisation originally switched to using the Procurement module of Fusion, that when they were on the Manage Requisitions screen, if they entered a valid Order number in the Order field, Fusion then auto-filled the Supplier field with the correct supplier details for that order. Is this something that existed back in version 20C? And, if so, how this can be turned back on?

Currently, as a user enters a valid order number in the Order field, Fusion displays a pop-up of possible order numbers that match what is being typed. But when the desired order number is selected, the user still needs to complete one of the mandatory fields (such as Supplier, Entered By, Requisition, or Item).
