How do I adjust steering expo on spektrum smart dx3 dashboard?

So as the title says, I can't figure out how to adjust steering expo on the dashboard. All I can find is trim centering and limits. Want to slow the rate near center. Several references and this chart say you can adjust expo with this transmitter and the dashboard.

Thanks, but unfortunately they do not mention it in that video. Pretty sure the information that you can adjust it when combined with the app is wrong. Apparently have to go with the "DX5 Rugged" or higher to get exponential adjustment on the steering servo.

Ended up getting a DX6 "rugged" from my local hobby shop and does what I wanted and more. Using it for 3 cars so far (2 Losi and one ARRMA). Could add my Axial crawler too but rear steer might be better with the switch on the original controller mainly because I am used to it.
