How to delete all videos from iPhoto after importing to iMovie?

[piatti]

Or FinalCut Pro for that matter.
I want it to be automatically deleted like you can on iPhotos but I don't know how.

Also how do I move files from FCP to iM?

Is the only way to do it by moving it to iPhotos first and thence to iMovies and then delete from iPhotos?
