Meteor JS: Conditional subscriptions, based on passed arguments, in Iron Router?

This is really two questions:

  1. Is it possible to conditionally subscribe to collections within Iron Router's waitOn option?

  2. Is it possible to pass in objects as an argument in Router.go()?

I am trying to reduce the delay in rendering a view, when creating a new post within my app. I tried passing in an isNew property as an argument for Router.go(), but had no luck:

// Router call after creating a new post
Router.go('postPage', {
  _id: id, 
  isNew: true, 
  post: newPostObject
});

// router.js
Router.map(function() {
  this.route('postsList', {
    path: '/'
  });
  this.route('postPage', {
    path: '/:_id',
    waitOn: function() {

      //This returns only _id for some reason.
      console.log(this.params);

      if (this.params.isNew != true) {
        return [
          Meteor.subscribe('singlePost', this.params._id),
          Meteor.subscribe('images', this.params._id),
        ]
      }
    },
    data: function() {
      if (this.params.isNew == true) {
        return this.params.post
      else {
        return Posts.findOne(this.params._id);
      }
    }
  });
});

After some digging, it looks likes Iron Router supports an options hash as a third argument in the Router.go() method:

Router.go( 'postPage', {_id: id}, {isNew: true} );

To access it in the route, you can use then use this.options. To get the value of isNew in the above example, use this.options.isNew.

you can only access Dynamic Path Segments by this.params. so to get this.params.isNew working you need to have it like this. 

this.route('postPage', {
  path: '/:_id/:isNew',
  waitOn: function() {}
  ...
});
