Gotta say, I went and looked at the first link you mentioned on Coffeegeek which discusses 'the problem' and I don't really understand 'the problem'. Coffee beans change from day to day, and even if you are being extremely precise on the gram scale while dosing loads and using repeatable distribution and duplicating machine variables etc, the grind setting will invariably change from day to day and even hour to hour depending on the environment. Grinder settings are always temporary.
Throwing those sliders into a general (approximate) location is all that's required. Sure the macro can typically be set to the same location, maybe two clicks down, but the micro slider only need within the right ballpark effort.
When setting up for a new espresso session after the grinder has been used for pourover I'll reset the grinder settings (all the way down and all the way up for both micro and macro) and then put the sliders in a 'gut feel' location for the bean I'm pulling. Then it's observe the shot I pull then I'll decide if I'm going to adjust the next shots grinder settings or maybe dose weight (or amount of pre-infusion time, pressure ramp, time on ramp, next pressure ramp and all the other schtuff involved with levers).
Grinder settings are temporary.
