Sorting by multiple facets

You can use orderasc to sort by multiple predicates, which will combine their orderings using lexicographic ordering. You can also use orderasc to sort by the value of a facet, e.g.

{
  asdf(func: has(edge)) {
    uid
    edge @facets(kind, index, orderasc:index) {
      uid
    }
  }
}

However, when I try to sort by multiple facets, e.g.

{
  asdf(func: has(edge)) {
    uid
    edge @facets(kind, index, orderasc: kind, orderasc:index) {
      uid
    }
  }
}

I get the error "Invalid use of orderasc/orderdesc in facets". Is there any way to order by multiple facets?
