In the same setting there is also “Smartpad White” mode. You can try that 
In that mode every white key is a different smartpad (I believe black keys are doubles, but you have to check).
In one “page” you have 8 smartpads on the Pyramid (the bottom 8 pads). You can use the arrows <> to shift octaves and access “more”.
But yes, if you are using an external MIDI controller you can have access to more smartpads (as many different note you can input).
Hope this helps
