In the video we have a functionality to increase the track of sfx length by stretching the region handles , but there are using mulitple segments to do so and the sfx track consists of multi tracks(segments of audio), now in my project i am using wavesurfer.js and i am using single segment for sfx, can we implement this functionality in single wavesurfer object. If yes then how? @katspaugh
