Blox by Blox Script deployment

We would need to know how it's possible to have the possibility to make specific federation.

Exemple : Commu X wants to be federated with Commu Y but only with bloxs JOB BOARD and COMMUNITY DIRECTORY

Could you investigate a bit to tell what we can do on this kind of case ?
