Prearranged pads in rekordbox 6.85

I've been playing with a DDJ200 in rekordbox, and I've been wanting to try the slicer, yet I can't use it with the performance pads of my ddj, and the only way to use it is to click on it. Is there any way I can change the fixed pads on rekordbox so I can use an slicer instead of a sampler?
