Purchase Requisition visibility / segregation

Hi,

We have a requirement to restrict requisition visibility within a Business Unit.

I am aware that there is a privilege that provides access to all requisitions; however, that is not what we are looking for. Instead, we would like to know whether it is possible to segregate requisition visibility based on specific criteria, such as Cost Center.

For example, requisitions created or submitted under certain Cost Centers should only be visible to designated users within the business, while requisitions associated with other Cost Centers should remain hidden from them.

This is just one example, and we are keen to explore the available options for controlling requisition visibility, especially since all requisitions currently reside within a single Business Unit.
