Solutions for 2D Animation Sync to Audio in Unity

I've been working with Puppet2D and the regular Animation Window for my animation solutions for awhile now, and it works great, but I'm working with some cutscenes now, and animating my character to any dialogue is a pain in the butt since I can't add an audio track directly to the animation window in Unity.

Does anyone know of any plugins or utilities that can replicate the Animation Window, but that includes a way to place an audio track on the timeline? I'm thinking something similar to Adobe Flash's timeline etc.

Thanks in advance.

 

Bump, if anyone can point me in a direction.
