Can I use my iPad as an input/controller device on DJay Pro for MAC.

Is there any software that allows me to use my iPad to extend the functionality of a controller/keyboard on MAC? I am not talking about Djay 2 for iPad or some stand alone product, but rather mapping more things like hot cues, sound effects whatever and have them at my finger tips instead of fishing around in the GUI of DJay Pro. Not every controller has everything. I would like to use my iPad to extend functionality

I never heard anything regarding this question. Perhaps I need to turn it into a feature request.
