Bulk update of Procurement Agents

Summary:

We have a requirement to update all procurement agents in Bulk. Recently, we enabled a DFF value for the Procurement Agent - Buyer Center., where each agent is assigned a specific value in the DFF (Lookup values). Currently there are approx 1100+ Procurement agents across multiple BU's. We need a method to update the DFF value for each Procurement agent - like a Excel file upload.
