Extending a block from another page

Question

My orignal website is a Onepager but I am creating a individual news page.

Is it possible to extend a block to another page taking over the content from that single? I have a block filled with a really big Matrix field which I cant have on my other page cause I only need a small amount of content from it. This content is placed inside a block so I need to extend just that block.

What I need is to extend the {% block navigation %} and not the entire page

See it as this:

{% block navigation %}
  {% for block in entry.blokken %}
    {% if block['opnemenInNavigatie'] is defined and block.opnemenInNavigatie %}
       <li>
        {% if block.navigatieNaam | slugify == 'news' %}
         <a href="/{{ block.navigatieNaam | slugify }}">          
          {{ block.navigatieNaam }} 
        </a>
       {% endif %}
      </li>
    {% endif %}
  {% endfor %}
{% endblock %}

And also this:

{% block content %}
    {% for block in entry.blokken %}
        {% include 'blocks/' ~ block.type ~ '.html' %}
    {% endfor %}
{% endblock %}

I'd just put whatever you want to share into an include. Also you shouldn't need the .html either as craft should find the file
