The MWE below creates a section numbering in the appendices of the form A.1, A.2 with A in small caps, but 1,2,3 in full caps. How can I either make A full caps or the number small caps?
\documentclass[twoside,paper=a4,fontsize=11pt]{scrreprt}
\usepackage[no-math]{fontspec}
\PassOptionsToPackage{style=arsclassica}{classicthesis}
\usepackage{classicthesis}
\setmainfont{TeX Gyre Termes}
\setsansfont{TeX Gyre Heros}
\begin{document}
\appendix
\chapter{Appendix Test}
\section{Appendix Section Test}
\end{document}
Edit: changing font is not an option in this case. A solution for this would be great!
