Bit travels through custom stock in g-code modeled in Fusion 360

1

I’m running a parallel cutting path to shape a guitar neck, on a piece of custom stock with an irregular shape that I also modelled in Fusion 360. I’d like to be able to set my zero at the bottom of the neck model, but when I import my g-code to Easel, the resting paths - both the first cut and the very end of the toolpath - run directly through the stock. Is it possible to import g-code from Fusion 360 to Easel, to set the zero at the bottom of the stock (the wasteboard, really), and to use a custom-modelled stock, without running the bit through the stock?
