CDJ3000 additional columns on display (with USB as source)

Detail, inc waveform is better now on 3000s (coming from 2000s), however seems you can only change the (category) data of one column (in Search/Playlist views). When being used to all the data of a laptop, extra columns would be useful, even if it meant scrolling to the right. One custom is a little limiting. Once you add Artist, you can't add anything else. So my suggest is another 1 or 2 columns please.
