Humanizing Values

So as my understanding goes, when you humanize a track (CTRL+H by default) it adds a random value to the volume/velocity, pan and delay to have a more human-input kind of feel to the notation. I use it all the time, especially on my drum lives and any melodies I have created. My idea is being able to change the positive and negative threshold of of humanization’s randomized values.

For example, if I input all my notes at 70 in the volume channel, and there’s 4 notes, my returned values may be 65, 7F, 6D and 71. I would want to be able to have those values be picked from a larger range below 70, and a smaller range above 70. This would apply to the pan and delay columns as well.
