Yes, the same technique will work with most page types. For example, if you wanted to display the latest 2 suggestions, you would create a new file called something like _latest_suggestions.html with and the following code:

{% for post in page.suggestion_box.most_recent_suggestions limit:2 offset:0 %}
<div style="font-weight: bold; font-size: 16px;"><a href="{{ post.url }}">{{ post.headline }}</a></div>
<div class="byline">
Suggested by {{ post.author.published_name_linked }} &middot; {{ post.published_at | date: '%B %d, %Y %l:%M %p' }}
{% if post.show_stream? %}
{% if post.public_activities_count > 0 %}
&middot; <a href="{{ post.url }}#reactions">{{ post.public_activities_count }} reaction{% if post.public_activities_count > 1 %}s{% endif %}</a>
{% endif %}
{% endif %}
</div>

{% if post.suggestion.content.size > 0 %}
{{ post.suggestion.content }}
{% else %}
<p>
{% endif %}
<div class="continue_reading"><a href="{{ post.url }}">Read more</a> &rarr;</div>
<hr/>
{% endfor %}

Then in the template of the page where you want the suggestions to display, paste in the following:

{% subpage "suggestion_page_slug" with "latest_suggestions" %}

Replace suggestion_page_slug with whatever the slug is for your suggestion page.
