Is it possible to have quizzes and surveys automatically linked to courses?

Yes. You need to link them to the template by navigating to Didactics → Collective Courses → Create from template and scroll down to the Defining Course Types.

From this screen click the blue button "Quizzes and Surveys" next to the template to which you want to link the Quiz/Survey.

At this point indicate which types of Quiz/Survey connect and save the changes.

Note: Courses already activated by this model will not be affected.
