Custom Overlay Steno

Hi Everyone,

First, I am interested in creating a steno overlay for the sensel morph.
The first question is has anyone figured out a way to generate an overlay like the ones that ship with Sensel, i.e., with buttons or raised sections? What I am trying to model is similar to the silicone steno keyboard available here: https://i2.wp.com/www.stenovations.com/wp-content/uploads/2012/02/Zenith-3.jpg?fit=2816%2C1880&ssl=1
I am going to use a one sensel for each hand.

Second, I need to create an application that will allow sensitivity changes similar to the changes shown in this video: Lightspeed 101 - YouTube

I will appreciate any pointers on how I can go about doing this.
