Moving clips back and forth from Sonar to Project5

Here's a stupid question:

What's the easiest way to move a groove clip from Sonar 5 into Project5 V2? It seems like there should be an easy, drag-and-drop-ish way to move clips back and forth, I think...

I'm pretty new to P5, but I'm starting to dig it for composition purposes. I've been playing around a bit with creating arangements using loops and such within P5 and then rewiring into Sonar to do the full-blown recording and mixing, etc. I like working in P5 because it's so simple and easy to deal with for the basics of song structure.

This has put a notion into my head of going back to some of my old sonar projects that had promise but never really went anywhere. You know, the ones that have like 80 sections of overblown, overly "written in the studio"-sounding stuff with twenty variations of every riff and half-baked string sections and a meandering 25-bar bridge that is supposed to somehow achieve a natural transition between a reggae-feel verse and 5/8 speed-metal chorus or whatever goofy idea seemed good at the time... the kind of song that is an overall disaster but with some really good ideas, far less than the sum of its parts.

It seems like P5's groove matrix would be perfect for taming such a beast, but I can't find an easy way to get all those riffs, loops, and audio clips to move back and forth between Sonar and P5.

Sorry if this is covered in the help somewhere, I looked, honest, but I'm better at audio than I am at software and I can't figure it out.

Thanks in advance for any help.

Cheers.
