Thank you for the pointer. Unfortunately, a search for 'scrheadings' in that document results in zero hits.
To achieve this, you have to modify your template file. As it uses the class scrreport class, so you will likely find the answer here: http://mirrors.ctan.org/macros/latex/contrib/koma-script/doc/scrguien.pdf
Searching "scrheadings" should lead you to the pertinent section.
