Really need to change songs by watch

On my Apple Watch, on the Equalizer watch app there is no next/previous button. The only items available are a separate play and pause which could be a single toggle button, the name of the song and artist, Presets, and a volume indicator which uses the crown to adjusts. I love this app and it is the only reason I changed my mind and did not return my Bose Quiet Comfort 35 headphones or Bose Soundsport Free ear buds. The sound was horrible with just the iTunes app on the iPhone, but your equalizer brought out the treble and base that was missing. While I can skip tracks from either the headphones or the ear buds, I would like to be able to do so from the watch as I use it to see what tracks are playing. I would happily give up the presets on the watch as you really need a bigger screen on the phone to adjust the equalizer. Just need a basic next/previous function added on the watch. Please let me know if it is already there and I just need to turn it on, but I have not found anything yet.
