当 authoryear-comp 样式中的年份相同时，如何使 origyear 全部打印在引文中？

Question

首先是一个 MWS，其输出如下。

\documentclass[american]{article}
\usepackage[style=authoryear-comp]{biblatex}
\addbibresource{\jobname.bib}

%add parenthesis around origyear----------------------------------
\DeclareFieldFormat{origdate}{(#1)}%\mkbibparens
%add origyrar in citiation--------------------------------------------
\renewbibmacro*{cite:labeldate+extradate}{%
    \iffieldundef{origyear}
    {}
    {\printorigdate}
    \iffieldundef{labelyear}
    {}
    {\printtext[bibhyperref]{\printlabeldateextra}}}
%add origyear and delelte the parenthesis around year in bibliorgraphy
\renewbibmacro*{date+extradate}{%
    \iffieldundef{origyear}
    {}
    {\printorigdate%add origyear in 
        \setunit*{\addspace}}%add space after origyear
    \iffieldundef{labelyear}
    {}
    {\printtext{\printlabeldateextra}}}%delete parenthesis around year

\begin{filecontents*}[overwrite]{\jobname.bib}
@book{bookot,
  location = {Place},
  publisher={ABC},
  author  = {Name, Given},
  title   = {One title},
  year    = {2001},
  origyear={1978},
}
@book{bookat,
  location = {Place},
  publisher={ABC},
  author  = {Name, Given},
  title   = {Another title},
  year    = {2001},
  origyear={1976},
}
\end{filecontents*}

\begin{document}
some quote from \cite{bookot,bookat}

\printbibliography
\end{document}

如你所见，我在引文和参考书目中添加了原文年份。然后当年份相同时，如何使引用中的原始年份全部打印出来，即使“名称 (1976) 2001a,b”变为“名称 (1976) 2001a, (1978) 2001b”？

Answer 1

引用命令的日期打印代码分布在几个地方，所以我们必须更改几行不同的代码

\documentclass{article}
\usepackage[style=authoryear-comp]{biblatex}

\DeclareFieldFormat{origdate}{\mkbibparens{#1}}
