javascript - Ember - sort array by multiple properties in multiple directions -

i need sort collection of ember models multiple properties, , not necessary in same direction/order. i.e. need sort property a in ascending order , property b in descending. there way accomplish this?

update

i tried setting sortascending property array, not working. after looking source seems functionality not supported out of box(yet).

in arraycontroller:

sortproperties: ["propa:asc", "propb:desc"] sortedmodel: ember.computed.sort("model", "sortproperties");

then reference sortedmodel in template's #each handler.
