Remap my Surface Dial and Surface Pen to do functions I want to map beside Microsoft's crappy mapping.

I have a Surface Book 2 which I bought in order to use Blender to do my 3D work, this means that I need to customize my accessories like the Surface Dial and Surface Pen in order to use the correct buttons for their shortcuts. Microsoft has a remapping setting for the dial but it is missing middle mouse click which I would like on my Surface Dial when holding it down and have the hold down function to become the click function. I am also in need of changing the Surface pen to make the correct inputs I want. The ideal programmer would make a program for me which could over steer the Microsoft shortcuts in order to add any of my own functions, fully customization of any button and within the range of $50 price.
