Keyswitches for Pitch bending?

can someone guide me how to create a keyswitch to pitch bend a playing note in one direction (up OR down)? and is it possible to have the bending speed determined by the keyswitch velocity (for ex. the higher the velocity the faster)?

Now of course I'm asking if there is a kind of a straight forward way to do this using kontakt's back end settings, but.... if such task involves kontakt language/scripting then don't waste your time on me
