Has anyone successfully used NCS Expert to code the amber coolant warning alarm to a lower temperature, much like the E39 crew have been doing for some time?

I've read in numerous posts that the N52 warning is set to 120 C, and the engine operates at different coolant temperature targets depending on the driving style. The eco mode target is 112 C apparently.
It should never go over 112 C as the cooling system is "allowing" the temperature to reach this high in eco mode, and provided that all is working properly it can reduce that temp to ~85 C within seconds if you change your driving style.
So there's no reason that it should ever go over 112 C unless something goes wrong, so if possible I'd like to set the warning to 115 C and have that extra safety buffer.
