Lets say i have a simple macro in `macro.html.twig`:

```
{% macro simple_macro() %}
    <h1>Simple macro</h1>
{% endmacro %}

```

Heres template layout.html.twig:

```
{% block body %}{% endblock %}

```

And main file `content.html.twig`:

```
{% extends 'layout' %}

{% from 'simple_macro' import simple_macro %}

{% block body %}
    {{ simple_macro() }}
{% endblock %}

```

Following code works, but i have many files like `content.html.twig` and i don't want to copy/paste `{% from 'simple_macro' import simple_macro %}` in a every single file. So i moved this line into `layout.html.twig`:

```
{% from 'simple_macro' import simple_macro %}

{% block body %}{% endblock %}

```

but it throws error:

`The function "simple_macro" does not exist in "content".`

Here's my question:
Is it possible to import macros in parent template and use them in child templates?

Thank you for your time.
