Ember route and navigation in modal, keeping parent route visible

Is it possible to have a route, say images/ show a list of images, and on click have an image open in a modal/viewer, say images/viewer/10, that has navigation (previous links to images/viewer/9, next links to images/viewer/11), updating the viewer modal while keeping the background images/ behind the modal as is, so that you can cancel the modal and go back to images/ without reloading the route?
