Feature Request - Saved multi-room volume settings

I use my Sonos speakers in the main floor of my house almost all day every day.  The speakers are ungrouped and I have one in my kitchen, one in the living room (doubles as the TV soundbar), and one in my office.  I am constantly moving the volume of each room up and down based on the current activities in the house.  I would like to be able to set and save volume profiles across all speakers.

Example: During the day while I am working from home, the music is louder in the kitchen and living room and quieter in the office while I’m on calls.
Feature Ask:
While speaker volumes are set at Kitchen = 10 Living Room = 15 Office = 6, I want to save this as “Work day” so the next time I want this configuration I can immediately recreate it.

 Use cases for this are plentiful, but by way of example I would create volume profiles for other things like “Cooking” or “Party Time” or “Game on TV” where I would want different volume levels in each room.

For additional consideration: This would also be a great feature to tie into Sonos voice controls!
Example: “Hey Sonos!  Play Pearl Jam everywhere with volume levels ‘Cooking’!”
