Round Tripping?

So has anyone figured out how to effectively doing round tripping, the closest thing I can figure out to do is select the clips you want to work with then copy and paste into a new "Project" and export it then open Motion and do your work there, then render and bring it back to Final Cut.

There has to be a better way.

That maybe the way at this moment. Apple kinda killed round tripping and introduced publishing.
My hopes are high they bring back round tripping or introduce a composite effect.

I really hope they can bring this back, or at least make the tracking features available directly in FCPX

I know what you mean I tried to bring that feature into fcpx by creating a effect in motion and you can add behaviors and publish them but you can not use the analyze motion behavior when making a fcpx effect.
