[SOLVED] DDJ-T1: Is it possible to map the Function, Advanced/Chained or Move/Hot Cue LED's?

I never used chained mode but wanted to experiment with using 4 FX units, the only problem being that I wanted to map it so that when I was controlling Effects unit 3, the chained light would be selected.

That is to say, instead of switching to chained effects, I would want FX unit 3 to be affected by using the hardware (turning the knobs would NOT affect FX unit 1, instead only FX 3.

I know how to do the mapping in terms of functions, but for some reason the LED's are not accessible when mapping. I then tried to map the Function LED and noticed that it also was not an option.

Is it impossible to map these LED's/change their function?
