Just noticed that you can copy-paste between scenes now. So I have loaded all my camera tapes into individual scenes, and made a master cut sequence scene.
Then I use Outliner to switch between camera tapes/scenes, I scrub through to the right shot and cut the clip where I want. Then I copy to clipboard, move back to master sequence and paste the selected clip.
I really wish there was a add marker key comand, like the old days. Its really anoying having to stop and menu for a simple function like that.
