Custom swipe handler for a list

I would like to have a swipe event on list items trigger an actionsheet rather than just exposing the ion-option-button. (Like the “Mailbox” app does when you swipe to snooze an item.)

Can I attach a callback somehow to the ion-list canSwipe functionality?

Alternatively $ionicGesture kind of works, but the deltaX threshold is set differently from that of ion-list canSwipe.
