Is there a way to do the following:

Have three separate audio tracks (positioned directly one above the other) and rather than place a marker and then navigate to each audio track in turn to create a mute point (twice -- once for mute point in and then again for mute point out), I'm wondering if it's possible to create all the mute points in at the same time (& then all mute points out) in a similar way that it's possible to split multiple tracks at the same time.
