How to use data-swiper-autoplay in ion-slides

I’m using ion-slides, which is based on Swiper.

I’ve gotten most of the options I need to work, but I’m using autoplay and one slide needs to play for a shorter amount of time than the others. According to the Swiper API, I could just set data-swiper-autoplay in my template, but it didn’t seem to work when I tried it. Is there an Ionic way to do this?
