Auto set user preferred Max Speed

Is your feature request related to a problem? Please describe.
Here's a thought. In the top left corner it starts of with the N/A for max set speed.
What if in the settings we could have a preferred speed we'd like to be auto set to when pressing our ACC on button. For me I would always prefer 65KM as most of our non highway roads are 60KM and OP won't operate below 64km(40mph). Being able to just turn on the ACC then resume when ready would be nice.
Also in regards to this too when we turn off the ACC completely the Max set speed is still displayed. IMO it should display N/A again as the last set Max speed is then misleading when you turn on the ACC again.
