Iso pads and drumpads

Hi everyone,

I have (I hope) a dumb question. Is there possibiloty to display with iso pads asceding notes without reapeating some notes? I mean it goes say from C1 to D#1 and so on in first row but in second row D#1 reapears and the following notes in second row are the same as in first one. Why on earth is this so??? It makes more then half of pads unusable, I mean they are redundant. Or can I display more the 8 drums pads? I have many drumracks with more than 16 sounds und so it woukd be really nice to be able to play it without switching
