All the "+1"-ing in the world is not likely to get Simplify3D to add this feature. Best bet is to open a support ticket with this request, or at the very least, put it in the specific forum section for Feature Requests.
Thanks for the requests, everyone! I can certainly see how this could be useful for larger pipeline processes. I've documented this as a longstanding feature request for our developers. I'll continue to monitor this thread for additional user interest.

I would really love to see this feature come to simplify3d. This is a major drawback not being to automate the slicing of files. It would be great to be able to setup simplify3d in our CI system instead of slic3r like we are currently using.
