There's no hack.
But ...
Extensive aerodynamic mods & higher tire pressure on my 2004 Prius (similar transmission to your Fusion) allowed me to cruise at higher speeds with lower engine RPM than normal, resulting in better fuel economy:

- eCVT: fantastic how it responds to drag-reducing ecomods. 1250 engine RPM at 50 mph on level ground with a low-torque Atkinsonized 1.5L is pretty impressive.

CVT's respond to ideally to mods, compared to manuals & conventional automatics.
I have no idea what RPM it ran at 70 or 80 mph though. I don't think I ever went over 65 with it.
