Your advice makes sense but only because, as you say, you do not know the RE, Which is 3D. Taking the connections outside, you can use multiple instances of Ambient Simulator to make other setup of speakers in case of 3D installations or live electronics for example 8.0, 10.2 and so on. Or smaller configurations such as quad stereo-compatible or 6.1 with Lh and Rh.

However, my intention is to provide a range of combinators with links included.
All the best
