Can Noise features apply with fade in and out?

This is more of a request but it would be nice if when enabling or disabling any of the noise features that they fade in and out. Currently when enabling the feature it's simply too jarring for baby and sometimes startles. This would also be the same when changing the volume.

Tldr:

Noise controls should behave like lighting controls fading in and out rather than abruptly turning on our off.
