Even lower Base Station volume

​There are times when I get up early and having my SS3 Base Station set to Low for volume is still too loud and wakes the house up along with the Chime function also set to Low. ​

​It shouldn't be too difficult to create a 4th volume level at 50% below "Low" and "0" volume to meet a "Whisper" mode? ​

​My household would really appreciate it. ​
