Chroma Keying in Motion

I'm an FCP editor who's never used Motion. But I need to do so in order to do a bunch of green screen work, as FCP's keyer isn't up to the task with this footage. I followed a tip from Larry Jordan about how to send a clip from FCP to Motion, get a great key, and have it show up back in my FCP timeline. Works great for that one clip. But I have a hundred similar clips in my timeline (drawn from dozens of long master clips). Wondering if there's an easy way to replicate the settings I created for that one test clip so it can be applied batch-style on each of the other clips in my timeline. Doing it one at a time would take forever.

I'm using Motion 3.02 in FCP Studio 2. Appreciate any advice.

You'd be much better off investing in dvMatte Pro (dvgarage.com) which works in Motion or FCP - and just set it up once in FCP, then apply it to all your clips using copy-paste attributes. Far superior keyer than anything stock in FCP or Motion.
