On the 200 you could set the display to show the voltage for each battery when charging. It's under the screen setting. So it's not the greatest. But at least you can plug it in for a few minutes and see what the voltage for each cell is.
It would be nice if the display option could be unique for each profile. That way you could set a profile then set it for the in use screen if you didn't need all 8 and didn't want to plug it in.
Those are both good ideas, I'd forgot about the "charging" display preferences.
And I've been griping for a few weeks about not being able to change the line selections on the fly, but separate choices per profile would be a workable half-alternative.
