There's no reasonable way to do advanced mappings on Android, at least. If you dig around enough you might find a horrible mess that technically can be tricked into doing things it was never supposed to do, but it's such a mess that I don't want to try to describe how to do it.
Hopefully it won't take too long until I've made some more progress on rewriting the controller code we use on Android...
