Is there a way to manage access on Supplier attachment categories

Summary:

We have business requirement where only Supplier Manager & Supplier Administrator should have access to view attachments at Supplier Profile. Current categories would provide access to either Buyer (To Buyer), Receiver (To Receiver), Supplier (To Supplier) & to Everyone (Miscellaneous).

Is there a way to create a new custom category and restrict access or to restrict access based on roles to the existing categories.
