Directionally dependent acoustic impedance boundary conditons

I am using the transient acoustics module, and I have two adjacent domains. Domain 1 contains an acoustic source that creates a sound wave which propagates into Domain 2. In Domain 2, the wave reflects off a surface and travels back into Domain 1. Is it possible to assign a Boundary Condition (BC) between Domain 1 and Domain 2, so that the acoustic wave leaving Domain 1 and entering Domain 2 encounters a different impedance BC than the reflected acoustic wave which is leaving Domain 2 and entering Domain 1?
I have already tried assigning an identity pair, but that does not work. You can only assing one Impedance value for the boundary condtion of an identity pair, it's the same as having an interior impedance BC.

Interesting question. I would also like to know a way to do this....
