Can we map UNSPSC codes to internal categories of multiple BU's

Summary:

Is there an easy way to map UNSPSC codes to internal categories for multiple BU's

Content (required):

We need to define Punchout catalogs for more than 20 BU's. UNSPSC code mapping (Manage Supplier Content Map Sets) is by BU. If we have the same supplier punchout assigned to multiple BU's, is there a way to upload mappings for multiple BU's?
