Passing an object as query-params parameter in link-to

Using the Route.transitionTo function, I can call,

this.transitionTo('posts', {queryParams: {sort: 'title'}});

So, say I have an object,

qpms={sort:'title'}

Now, I can make it,

this.transitionTo('posts',{queryParams:qpms});

I also know that, in the template,

text

won't work.

Is there some way to achieve the same effect as provided by the Route.transitionTo function, in the link-to helper??
