It sounds too complicated for me. I just put some numbers in the track name, in top->bottom, left->right order of knobs on the pedals. For example track name could be like "Lead Drive 0.5 1 0.7 0.5 0.5", so I don't need to look for this information. But I always record one pedal at once. So if there would be many of them...
P. S. There is plugin, that could store pictures, I don't know if it works well:
