Practice mode

From this thread I know it own't be possible to use a controller in Export mode https://forums.pioneerdj.com/hc/en-us/community/posts/204688723-Rekordbox-export-mode-controlled-by-DDJ-RZ

I would like to see some sort of practice mode where one can easily set cue points, loops and try things out without the track being counted as a DJ play and marked as played.
