Remaining versus Elapsed Time

 Hi,

I was trying the rekordbox dj with my XDJ-R1 and I loved this association everything was mapped automatically nothing to do except adjusting the cross fader rule to have it at through. 

Now my issue is that only Remaining time can be shown or the elapsed time not the 2 in same time and I am not able to jump from one to the other with a knob on the XDJ-R1 I need to use the mouse. Is there a possibility to map a knob for this?

Thanks
