4.0.6 - Relatd Track Preview: bug vs. omitted feature

Hi

I posted about this in my 4.0.6 feedback thread but wanted to bring it up again.  I have successfully mapped two buttons on my DDJ-RZ to "Preview Play" and Preview Skip".  This works when on the main track list, but when a track in "Related Tracks" is highlighted, the buttons do not work. Not sure why it would work in the regular playlists but not in related tracks, especially when both of those commands are supported in related tracks.  For example, we press the middle of the graphic to play and then press the >> to forward 20 seconds.

Seems like when they fixed the bug I pointed out with previous versions, they forgot to map it to the "Preview" command.

Does anyone else wish they had the ability to use midi to preview tracks?? Thanks
