If not, then the best option is to extend a little, save then extended a little more and so on.
That's point I'm interested in, too. I read in a post that if you shorten (in terms of compress not to cut) a segment the speed rises e.g. the average speed of the segment is 50kmh. After shortenig the segment to the half the average speed rises to 100kmh. Can this happen?
