What’s even worse is that we can’t combine mono-files to (any kind of) multi-channel format just by dragging them to the respective audio channel.
In the same vein, it’s a major PITA that Nuendo doesn’t allow for changing from (say) mono to stereo processing just by inserting a plug-in with the desired I/O options.
True … sigh … eg. Post-fader plug-in's routing gets lost in multi-channel tracks
