Is it possible to restrict users from booking to companies in a consolidated ledger?

We're trying to brainstorm the best way to prevent users from booking to companies in a Consolidated ledger that should be booked in a Primary Ledger. 

For example, co 100 lives in Primary Ledger 1, but the BSV has to be active in the Consolidated Ledger for consolidation.  That means people can post to co 100 directly in the Consolidated Ledger which they should not do.  Of course I know we can create a new responsibility and restrict the BSV's it has access to, but we don't want to do that.

Are there other ways (via configuration or perhaps personalization) to restrict users from booking to companies in a consolidated ledger?
