DDJ-RZX Waveform preview

Hey is there no Option that u can preview the Waveform?

I mean in the Centerscreen is enough Space to Show it.

U could even make it viewable in the other Screens.

The Advertising says you only Need ur PC as a storage with this Controller.

I think it would be a great Idea to make this Controller better and would be a great Way to make the Workflow much better.
