That type of functionality would be pretty rare to non-existant on an HD recorder. But, it’s mostly irrelevant too - you’d either have a punch-in on the track (in say one spot that you want to “fix”) which would result in still just one audio track to import, or a whole 'nother take (whether or not you record the entire length of the track being up to you) in which case you would wind up with 2 (or more) tracks (takes) which you would import each into its own lane in Cubase and then you would do what you want from there.
