Is there any way when notifying on a collection to only render new objects on the page ?

I have a template setup as follows:

<div children="@bind(vm.questions) @template('questionsTemplate')">
    <template name="questionsTemplate" var="question">

         </template>
</div>

We are using scrolling to load more records - when we load the second set of records we add them to the questions collection and notify in the View Model :

BindUtils.postNotifyChange(null, null, this, "questions");

This re-renders all of the questions in the collection even though some are unchanged, is there any way of avoiding this ?

Thanks.
