AutoShare Spotify add to music intent

I don't if this intent exists. I stumbled on some other Spotify intents, play and next, which work fine.

I want to press a button on my Pebble when I hear a song I like, which is linked to a Tasker task. This task sends the intent "add to my music". Equivalent of pressing the "+" button in Spotify appp. How should I go about solving this problem?

This could be solved by simulating press on the button, but that requires the screen to be awake, and my device's screen (S3, running ROM blisspop) can't be woken by Tasker. Having it constantly on is not an option battery wise and having it in pocket the touch screen will receive unwanted touches.
