Why doesn't LG's Android (V40 ThinQ) remember the volume level for each device used?

My Nexus 6p, on the same version of Android, would have separate volumes depending on which bluetooth device was connected, mainly my car vs my headphones. It doesn't seem to be an option anywhere, at least in LG's flavor of Android. Does anyone else have this feature, and know how to enable it on LG?

It remembers media, phone, ringtone/alarm and Bluetooth volume. The 6P didn't do it any differently, regardless of what you might think you remember.
