mapping basic parameters with midi learn (MPC Live 2)

hey everyone, I'm having a bad time trying to map all the buttons of a MIDIMix using Midi Learn on my Live 2 (updated to last firmware).
everything goes smoothly with volume, sends and mute, but seems there's no way to assign the "solo" and "rec arm" parameters on the MPC.
this looks pretty dumb to me as if I'm likely missing something, how is it possible that I can assign about 100 different parameters from tracks/pads/submixes/fxs to the MIDIMix, but I cannot assign the solo function on an audio track?
thanks in advance

aren't these SYSEX messages?

wish I could answer you but all my knowledge about midi is on cables and hardware.
anyway, after giving a deeper look in the web seems there is a well known issue with global parameters midi mapping on standalone MPC, since the device is able to assign every parameter to external controls but the software limits those parameters to the few basic functions I had available.
so the only possible way seems to work with ssh access and assign the desired parameters on the computer, then move the file to the MPC drive.
cannot really understand the reason behind these limitations, guess I will have to learn ssh stuff next days.
