How do you adjust the tune when your in Free Play and trying to drag race?

Seem like once your at the track, you can’t tune or am I missing an option somewhere?

When in “Free Play”, you can change the set up as a whole, however you can’t adjust specific parameters. In order to adjust gearing or suspension settings, you need to go to “Upgrade/Tune”. I usually tune on a “Test Drive” of the “Test Track, Full”, and use “Free Play” for reference times.
