How to program my keyboard’s numeric keypad?

I use a WASD CODE 104-Key Mechanical Keyboard with my MacBook Pro. (The MacBook Pro is generally closed and connected to my LG monitor.)

I'd like to reprogram the numeric keypad on my WASD keyboard so that it basically has two modes, which I'd be able to easily toggle between using a keyboard shortcut or by pressing the numlock key.

In the first mode, the numeric keypad would function as normal. In the second mode, the numeric keypad would be reprogrammed, e.g. the "0" key would replicate the ⌘+W key combo, the "1" key would replicate the ⌘+C key combo, the "2" key would launch an application, etc.. (This reprogramming should only impact the number keys on the numeric keypad, not the keyboard's top row number keys.)

Is this possible to accomplish with BTT? I'd be grateful for any guidance.
