It is currently not possible, but it could become possible in the future.
Please please please!!!
For me, and I’m sure many others, then this would be a massive time saver. I typically master a project/album in one montage. Once the analog captures have taken place and final processing is done then I bounce off the final masters. CPU hungry, post-analog processing plugins can take quite some time to render. Even on a fast machine. Being able to spread this via multiple cores would result in huge time savings for me.
