How to try out a plugin's example layout convieniently

I wonder how I can compile and flash the example layout of a plugin without copying it to .../Model01-Firmware/Model01-Firmware.ino. I want to debug a problem that appeared updating the firmware and having to copy the example layout would make things much more complicated.

For instance, the example layout of OneShot is in ~/Arduino/hardware/keyboardio/avr/libraries/Kaleidoscope/examples/Keystrokes/OneShot. Because there is no Makefile, I cannot compile and flash it there.
