Taigo Lane Assist ACC Question

Moin people, we recently have a Taigo as a company car. He has among others Lane Assist and ACC with VZ detection. With the newer VW we are practically ignorant. Have driven for years only Audi. Two questions: 1) The ACC overwrites my attitude at each traffic sign. I hire 75, there comes a 70 sign, attitude is overwritten. I hire 85, it comes free, although I want to drive still only 85, my attitude is overwritten and it goes to 100. In my opinion, too soon before the next sign is braked and gas is only given much too late after the sign again. Every normal person drives with 55-60 into the place and accelerates 50m before the exit sign again. Can you change it somehow or code it. In the Fzg settings I found nothing about it 2) The Lane Assist is rather a lane warning. Keep track does not really make it. We have the system in the Audi A4 and there the actively keeps the track mitt e. Do you only have to keep your finger on the steering wheel on long motorway stages and can drive like this forever without really having to steer. Is this a matter of equipment or is this system not available at VW? Can I encode something freely? Because ahrdware moderately has everything it needs for an Audi-like Lane Assist, the implementation is only on the software side. Question 2.5, Is there any information about what can be coded freely with VCDS or the like?
