Add Numeric Keypad shortcuts from a MacBook Pro

Is there a way to enter Numeric Keyboard keys on a Macbook Pro if I do not have an extended keyboard?

Am trying to add Touch Bar support for Blender ( Blender uses Numeric Keypad keys for several important functions but the MBP doesn't have a Numeric Keypad.

BetterTouchTool looks like it will let me map Numeric Keys to the Touch Bar...but I don't have access to a keyboard with numeric keys to enter them in the "Trigger Other Keyboard Shortcut" field.
