How to add stylesheets by twig template in Symfony - php

Question

I followed this tutorial to add sass support in symfony:
https://alexandre.salome.fr/blog/sass-compass-assetic-in-ten-minutes
So far, I have a stylesheets.html.twig with this content:
{% stylesheets filter="sass"
"css/main.scss"
"css/details.scss"
"css/talk.scss"
%}
<link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
that works fine, but how do I add more stylesheets when a specific *.html.twig is used? I guess I cant use blocks when using the filter function like this above.

Answer 1

For Synfony2 it should look like:
{% block css %}
{% stylesheets output='css/compiled/index.css'
'#MainBundle/Resources/css/editable.css'
%}
<link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
{% endblock %}

Answer 2

ok dimitrio, your answer directed me to the solution
first problem was, that the stylesheets.html.twig was included, and therefor I couldnt access and overide the block inside it, so I replaced it by use:
#base.html.twig
{% use "::stylesheets.html.twig" %}
{% block stylesheets %}
{{ parent() }}
{% endblock %}
and inside the stylesheets.html.twig
#stylehseets.html.twig
{% block stylesheets %}
{% stylesheets filter="sass"
"css/main.scss"
"css/basic.scss"
%}
<link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
{% endblock %}
Inside my specific twig I had to add content to the block
{% block stylesheets %}
{{ parent() }}
{% stylesheets filter="sass"
"css/specific/show.scss"
%}
<link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
{% endblock %}
It works nice, but isn't there a solution that is shorter for the specific twig? Iam looking for something like
{% addstylesheet 'css/specific/show.scss' %}
