Are user provided translations for user provided templates possible with the django template engine?

In my webapp, I'd like to allow users who want to deploy an instance to write their own templates. Specifically, I would like to include a template for a data protection declaration using the include tag and have this point to a location which users can define in their settings.
However, this would not be translatable, as all translated strings have to be in django.po and that file is in version control.
Is there a way to extend django.po, e.g. use an include statement to point it to a second, user generated translations file, similar to how I can include templates within other templates?
