YRV Turbo gearbox for sequential shifter conversion?

Was just looking around and came across some of the Kelisa YRV turbo builds in Malaysia. Most of them seem to use the YRV automatic gearbox which you can manually control with buttons on the steering wheel. So I was wondering if anyone had modified this system to make a cool and simple sequential shifter? Like keep the auto gearbox as is but make a manual shifter with these buttons or something. I think that would be a great option for a racecar Daihatsu.

Not sure it will be “racecar” quick shifting.
