It’s a tricky problem because if you drive with a separate set of tires in winter/summer or anytime you rotate your tires the mapping from the TPMS to each tire would have be updated.
I don’t know enough about it to know if or how any manufacturers solve that—maybe it’s something that you can manually reset when rotating tires? My car is a 2016 so I’m in the same boat and stuck with a blanket “low pressure” warning.
My 2012 car could report individual tire pressures for each tire. After a few minutes of driving, it would know which tire was witch even after rotating them.
It's not too difficult for the car to know which TPMS chirp relates to which tire.
