Number pad key assignment.

[codesnippy]

I am trying to use my controller in the program Blender 3D.

However Blender 3D distinguishes keys coming from the number pad vs the normal keys (1,2,3,4,5,6,7,8,9,0,+,-,/,.,*,up,down,left,right,page-up,page-down,insert,delete).
However I don't seem to be able to assign the number pad version of the keys to a controller button.

If this is not possible it would be nice for my use case if this could be added to the program.
