Non-Static Brows

When I upload an audio and "Compute Lip Sync Take From Scene Audio," everything is great, save for the eyebrows. I've tried creating a behavior, such as using a shortcut to move them to expressive positions, but it look extremely choppy, especially compared to the rest of the face. Is there a way that an expressive eyebrow behavior can be added to the Default Puppet Track Behaviors, such as Eye Blink Frequency? Thank you for the help!
