group volume control

I really miss not being able to control group volume, by room, independent of overall group volume. In the new update there are multiple steps to follow just to change volume individually in each room!! Also, the ability to mute any single room isn't there anymore??!!  The only option there is to remove that room from the group  that doesn't make any sense!! 

The new update is disappointing for this reason, but not this reason alone. I wonder what was the underlying reason to take that ability away??
