S2U2- how do you setup slide to ignore?

[eptd]

I think I've come across a thread here where you can set up S2U2 to have slide to ignore AND slide to answer on the same screen. I think it was slide to the right to answer, slide to left to ignore. After searching, I only came across posts that say you have to remove the slide to answer feature to see the answer or ignore buttons. Can someone tell me how to do this? I always click thanks!
