Queue message filtering

Hello,

We are on MRG 2, AMQP 0.18. Is it possible to do queue filtering by message's source/sender.

We are merging 2 environments into 1. However, we still want to ensure that certain messages with the same topic coming from A environment, is not consumed by B environment Back Office. A and B Back Office have the same address however. So the routing key is b.mycomp.commontopic.
