Ability to change playback speed in android auto

I couldn’t find anywhere else this has been requested, but I would really like to be able to change playback speed for synced “music” in android auto. I keep audiobooks and music inside of plex and keep both synced. I listen to audiobooks at a faster speed than regular music. On a longer car drive I am unable to switch from music to audiobooks and modify playback speed.

I use pocketcasts for most of my podcasts, and an interface similar to theirs would be great.

Click on the 3 dots
options come up, one of which is playback speed.
each tap on that option increases speed by .2, until you reach 2x, and then instead of going to 2.2 it goes back to 1.
