Backup/Restore does not change manually added links to the same course

I'm creating a site with simple navigation for early elementary students. Each course is to be set up so that students see a number of large icons under topic 1. Each icon links to a new topic (which in turn has a "back" button to topic 1. Only one topic is to be visible at a time (initially topic 1)

So course links such as http://mysite.edu/course/view.php?id=34&topic=1, http://mysite.edu/course/view.php?id=34&topic=2, http://mysite.edu/course/view.php?id=34&topic=etc. are used extensively throughout the course. Works fine ... But I want to be able to clone the course for multiple teacher/grade scenarios. ... so, when I backup and restore to another course (say id=35), all of the links remain pointing to id=34. I'm creating these linked icons using labels, but a test of a the same html in a course webpage also failed to change the urls.

Can the core code be modified (or a fix be provided) to allow for the conversion of all urls (that point to course A ) when it is restored to course B, C, etc.?

As Eloy stated in http://moodle.org/mod/forum/discuss.php?d=148686, it would be great to have some filter doing that work, exactly like the "Activity Names" filter does, but working on sections.
