Is it possible for django template url direct to another project?

I have two projects called blog, user_auth, both are all django projects. In blog project, I need to do a user authentication. Of course we can do it in current blog project like the following.

<span class="sign-in">
    <a href="{% url 'blog:sign-in' %}">sign-in</a>
</span>
<span class="sign-up">
    <a href="{% url 'blog:sign-up' %}">sign-up</a>
</span>

The question is if we have more projects which also need to do user authentication, we will have many repeated codes.

Here user_auth project is to manage all the projects' user authentication. My question is if we can use {% url %} in a templates in blog project to direct to user_auth project?
