How can I sync audio in Premiere with a comp in After Effects? I've got a track in Premiere that's composed of a lot of screen shot stills and there's an audio track that narrates across all of them.

As the narrator talks, I want to illustrate what she's saying with FX from AfterEffects. For instance, when she mentions a specific region in the image, I want to animate in a highlight like so:



But I can't figure out how to sync the audio with the effects. If I replace the one still image with my AE comp, then I have no audio and I don't know when I need to apply the highlight. 

The only other alternative I can see is to finish the entire track and then import it, audio and video, into AE and apply the effects. But then I'll have a massive AE track with hundreds of layers, each one targeting a different part of the timeline, and that seems like it will be very hard to manage.

Is there a better workflow or technique that I could use here?
Go to the in and out points of the clip and add edits (ctrl / ⌘k) to the audio track, so that the section of audio underneath the image clip you want to replace is separate (don't worry you can rejoin it later). 

Now select this audio and the image clip and replace with an After Effects comp (using the right-click menu and choosing Replace with after Effects composition). The new AE comp will have the selected video and audio clips in it, so you can synch up.

If you don't want your audio to be chopped up, just alt-click the audio that comes from the AE comp and delete it, then stretch the ends of the original audio clip to cover the gap, select the match-cut edit and hit delete and the added edit will disappear.
