Enhancement for cdj

I use the random function in cdj quite a lot. However, I would like the ability to include/exclude certain catagories from playing. For example, when listening to classical music, I like hearing the entire CD, so therefore I don't want them to be on a random selection.

Also, I've got some dts cd's. Again, I'd like them not to be selected (this is due to my amp working out it's dts ok, but it doesn't automatically switch back to pcm afterwards).
