HELP - DDJ200 and Headphones CUE

I don't have good speakers so I normally play with headphones all the time and that's causing me a problem.

The DDJ200 doesn't have a way to adjust the mixing volume

I need to have the master cue active all the time to hear what I'm playing and the CUE button for the other channel when I want to mix a new song.

When I have the master cue and the cue for the new song, the mix volume is 12" so I hear both songs at the same volume, maybe for someone else that's not a problem but for me and my headphones it is.

There is no way to change that, I can only go with the mouse do it manually FOR EVERY SONG! Super annoying.

The difference is huge, when I mix at 12" most of the time is hard for me to know what's going on but giving volume priority to the new song, mixing is so easy! I can't believe it. I've been mixing at 12" for months ...

I just can't change it, is there a way to do so? I don't want to manually change de volume with the mouse for every song.

When I have the master cue ONLY, the mix volume is not 12" but the moment I also add the cue button for the new song, it goes 12".

I want to have the master cue and the cue for the next song active, BOTH! And the mix volume to stay as it is and not move to 12". Is it possible? I couldn't find anything in the options.
