Doors NG - permission to deliver to a specific stream

Hello,
    My use case:
- I have 2 user and 3 stream (A, B and C) in my Doors NG project.
- the user n°1 can work on the stream A and C but not on B
- the user n°2 can work on the stream B and C but not on C

Is it possible to setup something from DoorsNG with GC to have this previous use case  ?
I have tried with "create change set" permission and to check the stream option "changes must be made in a change set" but it seems not enough.

Thank you in advance for you return

Best regards

David
