2D music or binaural recordings with FMOD and resonance audio

I am making a game where I would like to use resonance audio for 3D sources and also for some ambisonics recordings. This works very well for me. The problem is now that I would love to include both some 2D music as well as some binaural stereo recordings I did (not ambisonics). What is the best approach to play these sounds when using resonance audio? - The best approach for me would be to use two listeners, but I guess this is not possible? - Is there any alternative way to come around this?
