Z3 = Z2 + Add 9-12 extra buttons for thumb

Hi, I like to keep my left hand free and only use my thumb if possible. I also use a special ergonomic keyboard which makes half the keys separate. 

I'd love to have add an extra 9 or 12 programmable buttons for my right hand thumb to: switch weapons (1-4), throw grenades, and activate multiple abilities. 

For context: I use moba mouses in games like Halo and Battlefield 6 so I can quickly switch between soldiering and piloting aircraft with 12 keys (7 and 9 to yaw, 8 & 11 to pitch down/up, and 10 & 12 to "roll" but with the Z2 gyro tilt feature, I only need 6 well placed buttons. Basically I want the mouse to have the power of a flight stick with the portability of a mouse.
