Is there a way to make the master LEDs work in DJM-101 controller with Djay Pro?

Everything else is working, but since there is no knob I can map the LEDs with, I don’t know how to map them to Djay Pro’s master output.

I mean, you can only map knobs and faders in the MIDI configuration window, right? Or am I missing something?
