No there is no sense in it. You could however switch your programmable output on the LM1 to lambda and have it output 0.70-1.10 lambda and then enter that on the list portion instead of the transfer function so that 0v = 0.70 and 5v = 1.10. That will increase the resolution of accuracy on your analog output. I also used to have an LM1 and did this to narrow the range down so that small voltage fluctuations wouldn't affect the reading as much.
There is no need for commanded lambda because you have EQ Ratio. The EQ like stated earlier, is either equal to lambda or the inverse so there is no need in wasting a custom PID spot for commanded lambda when it can be integrated into the lambda error custom PID.
If you wanted commanded lambda just for a visual then you could make a custom PID named commanded lambda and it would either be 1/[PID.6010] or [PID.6010] depending on which OS you are running.
