Adobe Illustrator CC: Persistent color mixer in gradient editor

When double clicking a knot in  Adobe Illustrator's gradient editor, it brings up a RGB color mixer. Most of the time, I switch this to HSB (to create a gradient in a certain tint).
But each next knot I double click, AI comes with the RGB picker again. Why doesn't it 'remember' that I like to use the HSB-picker?

My request: let the gradient tool bring up the last chosen color picker, and not default to RGB.
