Some one-move edits are possible. Multi-select clips, right click -> Adjust Sound Events lets you change gain (relatively and absolutely) and fades for multiple clips.
But changing the length of multiple clips isn’t so easy. You can right-click -> Adjust Timing, then use the Quantize mode of “Quantize start – Set length”, and preview/play with the values (including the “Grid” value)… But this won’t set all clips to an equal length; instead it will kind of adjust them by an equal quantized amount. This is cool for tidying clips up relative to the grid, so it might work for an arrangement-based drum machine frenzy. But otherwise, no I don’t think so.
