Django south and django-admin-tools issue with migrations

Question

Django

I have a project that has an app (myproject.apps.menu) and I also have a django-admin-tools that has an app called admin_tools.menu.
If I run the command:
manage.py schemamigration menu --initial

Then the file appears in the admin_tools.menu.migration folder and contains the models both myproject.apps.menu.models and admin_tools.menu.models.

I have also tried using the 'SOUTH_MIGRATION_MODULES' option. In this case, all models of both applications also appear in the same file.
