Downright and downleft on mat?

For stepmania 5
Recently, i bought a USB mat for stepmania and I have assigned the up, down, left, right, upleft and upright. However, my mat has up, down, left, right, upleft, upright, downleft and downright, but i haven't found an option for assigning downleft and downright. Is there anyway i can do that?

The downleft and downright buttons cannot be used in dance mode. You can, however, use them in techno mode with the appropriate noteskin installed.

Alright thanks. I have assigned all arrows but not center (not sure why i cant do that) I just need some techno songs. It only comes up with roulette :'D
