好的,我距离解决方案不太远了:
\DeclareSectionCommand[
afterskip=1.5ex plus .2ex,
beforeskip=-3.25ex plus -1ex minus -.2ex,
font=\usekomafont{subsection},
indent=0pt,
level=2,
tocindent=3.8em,
toclevel=2,
tocnumwidth=3.2em,
tocstyle=section,
counterwithin=section,
style=section
]{gp}
我所需要的前缀:
\renewcommand*{\thegp}{GP\arabic{gp}}
