How can I put some centered text directly under the headsepline?
\documentclass[fontsize=14pt]{scrreprt}
\usepackage[margin=1.75cm,
includefoot, includehead,
showframe=false
headheight=2\baselineskip,
]{geometry}
\usepackage[ headsepline,footsepline]{scrlayer-scrpage}
\chead{Some stuff here... \\ Some stuff there...}
%\addtokomafont{headsepline}{\centering Text directly under headsepline}
\begin{document}
Content...
\end{document}
\chead{wombat\\capybara\\\hrule \\ Mara}
instead (untested)
