Enabling/Disabling assists from the tuning test drive

The last few days I’ve been delving heavily into tuning for the first time and I just noticed that when you select test drive from the tuning screen you aren’t presented with the assist options tab once the track is loaded. Am I just completely missing how to enable/disable these or are they really not there? This seems like a pretty big omission and is quite annoying to back out of the track completely just to toggle TCS on/off

You have to back out, you’ve always had to back out to change it.

Definitely something they should add in a future patch.
