Ember.js Routing: 'refreshModel: true' on queryParams without updating child route model

I would like to update a parent route on queryParams change, but not any child routes. To update my parent route on queryParam change, I use refreshModel: true.

According to: http://ift.tt/1B8X3Tz, refreshModel: true will cause child route models to refire.

Can I opt out of this behavior?
