Substance Designer Integration

I use Substance Designer to create luma mattes for complex video transitions. Currently the workflow is to bring an SBSAR into Substance Player and export an image sequence. Then I have to retime it in AE which can be a bit cumbersome.

It would be great to have SBSAR integration in AE similar to the integration in Photoshop Beta. But it would be nice to also keyframe exposed parameters in AE as well.
