Preset volume on speakers/groups

Hi,

I really miss the function to set pre-defined volume levels for different groups of speakers.

for instance I have a beam, a five and a roam all grouped together in my living room. I use them separately (like beam for tv and roam on the go) but playing music in my living room I want to use them together in a set volume and not have to manually adjust them

this topic seems to have been around in different threads for years without any action taken.

is there any plans to implement such a solution to the system? It seems like a fairly easy SW adaption.
