Choosing Cut Range from the Edit menu will copy all information within the anchors on your Count Track, and remove counts and range from the drill. Once a range has been cut, the Count Track will adjust accordingly. All performers and drill data (including but not limited to: transitions, text boxes, prop locations, arrows, etc.) are copied.
To cut a range of drill, spread your anchors for the section of drill you would like to cut, then choose Edit and Cut Range.
