How much do you adjust your wake plate (trim tabs)?

I think that's an MC with surf tabs factory installed , yes they do work

I wonder if those MC tabs can be set to "automatic mode" and adjust the list of the boat for offset weight, to keep it perfectly level while wakeboarding or skiing, or whatever. Then also can be set to manual mode where you can cause the boat to list for surfing, etc. With the cost of a MC, I'd expect nothing less.
