Backbone.Marionette Fade Transition for only specific regions?

I know I can override all regions to add a fade transition by using the following.

Marionette.Region.prototype.open = function(view){
  this.$el.hide();
  this.$el.html(view.el);
  this.$el.fadeIn()
}

Is there a way to only override specific regions or views? I have certain regions in my layout that I would like to be able to fade in while other regions should be rendered instantly.

Thanks,
