It is possible to set up a dummy course and use an iframe embed to 'window' content from another course.
You can get the courseids from a course storage report, for example, and then build your iframes for individual courses in individual spreadsheet rows linking the specific requirement (eg home page, syllabus, assessments) to the iframe.
You then copy the code into the htmls view for as many links/pages as you like (it gets wobbly at about thirty frames), and the pages will all appear open.
If you want to be clever about it you can use <details><summary> tabs to 'concertina' the iframes open and closed.
Have fun !
