Midi Learn MultiMidi Request;1 midi channel per element Rapture/Dimension

Had hoped my multitimbral control keyboard could make use of different midi channel presets for 16 knobs to control each element on a seperate midichannel,but it seems midilearn doesn't recognise different midi channels,even in multitimbral mode!
 
o.k so i've just managed to squeeze 16 knobs x 6 elements + global in Rapture,
avoiding pre-used cc's,out of my alloted 128 cc numbers on 1 channel, but as ever,
i want more as there are many more than 16 controllable parameters per element,& i was looking to getting behringer brc2000 or similar "heavily encodered" affair in near future.
 
would anybody else support a request for multimode midi learn ?
an additional great feature would be if "element" & "mod" buttons could be assigned cc switches, so a row of buttons on hardware controller could change element/mod screens in focus on virtual device.
