Show all waveforms when adding tracks to the mix (Rekordbox)

When adding new tracks, one has to select a track to have its waveform show at the bottom and scrub it.

It would be nice to have these available in the track list where there is plenty of room. I though admit that generating these waveform is not a lightweight task, as it's usually done on library. Maybe there's a way to grab these waveforms from Rekordbox library if possible ? That would be great as I'm usually able to tell what kidn a track is only by looking at it...
