Mapping Mod and Pitch bend controls to Akai Mini knob in Ableton?

[einsteinx2]

I'm in between full sized MIDI keyboards at the moment and picked up an Akai APK Mini to use for the time being and as a travel controller. I love it but it's missing the mod and pitch wheels that most keyboards have.

Does anyone have any idea how to map those functions in Ableton Live to two of the Mini's knobs? I keep reading online that it's possible and easy to do, but I can't figure it out. When I go into mapping mode I can't seem to select the mod or pitch bend envelopes to map them.

Also, side question, is anyone aware of a standalone mod and pitch bend wheel controller? Like literally just those two controls as they usually are on a keyboard but by themselves?

No one knows if it's possible to do this?
