Link Audio and Animation in sequencer

I’m trying to see if I can link a sound file to an animation file for the sequencer.

Say I have a face anim and a VO audio file. The idea is that I would create this “link” and in sequencer I would be able to slide the face anim around and the vo would stick with it.

I know I can grab the audio and anim blocks and move them together. I was just wondering if there is some more clever way using timecode or somehow embedding the audio in the animation.
