General help

Using Moodle 3.3.4, I want create a template course, i.e. a course that teachers can copy and adjust to their needs. In this template course I want to include internal links. That is, in, say, a Lesson activity I want to have links to several Choice activities.

How I did this now is through creating explicit links to the desired pages with Ctrl+k. 

However, this does not work when using the course as a template. That is, when teachers copy the template course, the links in that copy are not within that copy of the course but they link to the original template course.  

Even worse, when changing the preliminary url to a more catchy one, all of the links would no longer be valid. 

Is there a way to fix this? I.e. is there a way to add links within a course which are not dependent on the url?
