Reverb Zone question

So I just bought Unity pro, and was checking out the reverb zones, and was wondering if it would be possible to change the shape of the zone from a sphere to a cube. It seems like this would be a better option for aligning it up when using it with different rooms and buildings, so the sphere isn’t outside the building or room walls and having the player still hearing the reverb from that room when he is standing outside of it.

Did you ever get an answer to your question? I’m grappling with the same issue. Thx, Gunnar
