As someone previously mentioned, either the downstream customer announces the more specifics or you create them with a null route.  But the null route will show a different origination ASN than the customer's.

I was referring to the ability to inject specifics that are not in the
routing table. This is available in Cisco IOS.

You can inject specifics that're not in the routing table by the use of a null route.
