How to set recording to only keep full length takes?

In SX3 when I record my singer over looped portions of the song I’ll often start the recording at the last bar or two of the part. So basically if I have a 16 bar chorus for example I’ll place the locator at the beginning of bar 14, press record, and when it loops back to the start my singer starts singing. With SX3 the little bit that gets recorded before the first loop over isn’t kept, only full takes that go all the way from marker 1 to marker 2 are kept, so even the little bit that is left (since it’s starting a new take) when I hit stop isn’t kept either. It’s nice and clean. With Cubase 6 I’m finding it’s recording and keeping everything which I don’t want it to do. I don’t need to see those small pieces of pre and end recording. Is there a way to set Cubase 6 to act like SX3 did and only keep the full marker to maker takes?
