Correcting wrong orientation of H3-VR Ambisonic A recording for 5.1 rendering.

Hi.

I have a little problem regarding a recent recording I made. My H3-VR was suspended from 4 fishing lines over the performance space. Trouble is, I hung it facing the 'wrong way'/ It is easy enough to resolve this in the stereo and binaural derivations, but how do I resolve the problem for the 5.1 surround derivation (each derivation performed via the Zoom Ambisonics Player). I use Sound Forge Pro 11 for further editing. My guess would be that I should use SFP11 to swap channel 1 with channel 2 and channel 3 with channel 4 but what about channels 5 and 6. I suppose I could try a spectral analysis of those channels to determine which is the sub-bass and which the centre channel. What I would prefer, however, is to know how to save a 180-degree horizontal reorientation of the Ambisonic A format I recorded in.

Can anyone here offer a solution? What am I missing in the manual?

[I should, perhaps, have pursued my own route to a solution by carrying out a spectrum analysis before posting. It looks like its channels 3 that holds the centre channel, and channel 4 that holds the sub-bass when the 6 channels of a 5.1 resolution are opened in Sound Forge 11. However, I will leave the post here in the hope that others might benefit from it, or offer alternative solutions.]
