render 6 wav split - why can't?

any other programm can render 6 wav split for 5.1, but Relove after so many versions and never learned to do such a simple, but so strongly necessary function. I certainly understand that it's possible to convert Clip Info from 5.1 to 6 mono, and then in turn to render each channel in a separate wav.
But why then it was necessary to build FairLight in Resolve, then normally render 6 wav split through crazy crutches?
Once you have built in Resolve a serious tool for working with sound, then the renderer tool must match.
Is not it so difficult to add a simple option to output 6-7-8 split mono wav?
