python - django multiple templates nested extends

Question

There is now a page.
base.html
data.html

index.html

Now index.html extends base and blocks base information.
Here comes the problem. How to extend data.html? Django does not support the extends 2 syntax by default.

# index.html
{% extends "base.html" %}

{% block source %}

    {% extends "data.html" %}
