Rekordbox functions not working with DDJ-REV7

I acquired a DDJ-REV7 controller after verifying that it is now supported by Rekordbox.
However, during my first uses today, I was unable to get some key Rekordbox functions to work with this controller. Could you please inform me if it is possible, how I should do it, or if these functions are simply not supported by the controller in question?
• CUE Button / Temporary CUE:
That CUE button found on all CDJs and most controllers, usually orange and located very close to the PLAY button.
The controller does not have this button physically. I tried to MIDI map it, but it did not work with any button I chose. I then noticed that, in the software itself, the button disappears when the controller is connected. It doesn't even work with keyboard shortcuts.
• Track Preview:
Previewing tracks via the waveform, without needing to load the track onto a deck. By clicking on the waveform, with the track still listed in the collection/playlist, I could usually hear the song without even needing to load it onto one of the decks.
This function is not working with the REV7. In the audio output options, it only allows me to set channels 1, 2, or AUX as an "Output Preview" option, which makes no sense because when I click on a track to listen to it before loading, the sound comes out of the main channels and consequently the master, causing everyone to hear what only I should be hearing.
