Room correction using your iPhone and HouseCurve

I had good results with manual EQ using REW for measurements in the past and am eager to try out house curve to create a convolution filter for roon.

As far as i understand, HouseCurve produces a monaural WAV file, that will be applied to all (both) channels.
From my experience, i need different corrections for the left an right speaker because room modes are triggered differently by both speakers.
So i assume the way to go with HouseCurve will be to measure both speakers seperatly and create individual convolution files for both speakers. To ensure level matching, the target curve needs to be manually fitted to the same level during both measurements.
As a final step, the individual wav files need to be merged together ton a stereo wav file using Audacity or similar tools. Correct? Missing something?

Does anyone have tried this already and could share his experiences with this?
