Roundtripping with Premiere Pro?

I'm trying to simplify my video editing workflow and would like to start using an iPad to do more. Some of the videos I edit are simple and others can be complex. I've tried using Rush and found it great for simple things, but I often need Premiere.

If I start in Rush and bring it into Premiere I knw I can continue editing from that point on, but can I send it back to Rush or do I have to stay in Premiere once I'm there? Thanks!
