As far I know, it's not possible to set custom initial touch state at keyboard power on. Maybe it can be done by creating some "default" registration and loading it each time after keyboard is turned on -but that's just not the same.
I see customizing initial touch as something permanent. We adjust sensitivity according to our "way of playing", because some have more "heavy" fingers than others -that's why this setting exists. And our "way of playing" doesn't change from one song to another (it might change over the time, though). In short: keyboard should be able to remember custom initial touch settings as default.

Yes, but that's just a shortcut to set new initial touch values (needed to be done every time we turn keyboard on).
