I have a face performance captured with Live Face, and there are a couple of weird blinks and eyelid flutters that I'd like to get rid of.  Is there any way to access the base keyframes of what was captured, in a similar way to how you can edit the keyframes on the Base Layer of a body motion capture clip?  

When I twirl down the Expression Layer, I only see the keyframes that I set on top of Live Face's capture.
