Occasionally someone will pick a track I like and I wondered if there was anywhere in the controller for me to save the track to an existing spotify playlist or an apple music playlist.

Head into the Now Playing screen on your mobile Sonos Controller app
To the right of the Track Title, you can find a "..." which brings you a pull-up menu
Right under the "Spotify" header, the first option should be "Add Song to Spotify Playlist"
This will allow you to add this track to any Spotify Playlist. At the bottom, you even have the ability to create a new Spotify playlist. I have a playlist called "Solid Finds" for tracks that I have stumbled upon that don't quite fit in an already existing playlist.
Unfortunately, Apple Music does not have this functionality. In this case you may want to use something like Shazam which can take tracks you've "Shazam'd" and puts them in a playlist on Spotify,
