If your normal cold starting pressure for daily driving is 32, I'd lower it to 30 and target 35-36 while the tires are hot on the track (use your tire pressure display in the instrument cluster if your car has that, or measure with a digital tire gauge as soon as you get off the track). If the pressure while on track exceeds 35-36 in one or more tires, then let out however many pounds it was over before you start the next session. Monitor and repeat as you drive the rest of the day.
Don't forget to add back air at the end of the day so your tires won't be low after you've left the track.

I'm in Houston, TX and it's been hot as hell in here. At the track, it will be even hotter I'm sure. My cold start pressure is 32 as said, but I do notice that by just daily driving the pressure eventually goes to 34/35psi. I will mark these numbers and I guess for the tires I can just test it out on the day. Start with 30 and see where it goes from there.
