Reply to Traktor Advanced FX Mapping question - is this possible?

I want to assign different buttons/keys to instantly load specific FX into the various FX banks. For example, pressing C3 will load the Slicer, D3 will load the Reverb etc. I can only see options to allow 'inc' and 'dec' which allows scrolling through the different effects but no way to achieve specific selection of effects.

any ideas?
