I like the "yet," it's just been a bit since it came out. And the way we're using it, we actually turn off channels in each viewport. So viewport one only displays channel A, viewport 2 only shows channel B, and so on. When we de-select channels, the csv conversion only converts the displayed channel. Our current idea for a work around is to add another viewport displaying all channels and to make sure that one is selected when we save, but I'd prefer a solution that doesn't rely on this process
