Staged Upshifts.

Found this little video on how the ZL1 (and other '12 GM cars) used staged upshifts: http://www.youtube.com/watch?feature...&v=ctSo0aZ-SN0

Under the "show more" on that page:

"For 2012, GM powertrain engineers implemented a patent-pending software algorithm that improves tap response time by up to 60 percent compared to the previous system. No hardware changes were required for the upgrade.

By staging hydraulic pressure in the clutch for the next gear, the new control module algorithm reduces tap delay for the 1-2, 2-3, 3-4, and 4-5 up-shifts by 200-300 milliseconds. The system anticipates shift requests based on current gear, throttle, torque and speed. By pre-filling the clutch for the next gear, the tap up-shift response is near instantaneous.
"


Since no hardware changes are required, can the trans on a '11 (or earlier) be tuned to stage the upshifts the same way?
