Actually when I say not possible out of the box, I should really say without having to write some custom code. Since JQuery is built in, you should be able to write your own JQuery function that gets called when the switch drown down is changed (see: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#modeladmin-media-definitions). This function should make an ajax call to a custom view in your model admin (see: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#adding-views-to-admin-sites).
Overall you will have to write a javascript function (JQuery) and a custom view for your ModelAdmin. You of course don't have to use JQuery, but it is included by default in the admin and is quite popular.
