Profile option 'PO_PRC_AGENT_CATEGORY_ASSIGNMENT'

Summary:

As per the description of this profile option;

Allows procurement agents to designate a default browsing or item category used to filter data when they access the procurement dashboard.

But, i want to understand which Procurement dashboard does it impact?
I put up a category for a user in the profile option and checked if it impacts the Overview page of Purchase orders in classic UI for that user, i couldn't see any difference. Where else does the profile option impacts the output?
