我们的模板是如何实现，同一作者不同年的文献在引用时姓名共享，年份逐个罗列？

您好，我在使用我们模板时，我们模板可以将同一作者不同年的文献，在同一处引用时，其姓名共享，年份逐个罗列。但是当我自己使用biblatex-gb7714-2015宏包时，我没法实现这一点。比如：

\begin{filecontents}[overwrite]{test.bib}
@article{park1960,
  title = {Carbon Isotope Fractionation during Photosynthesis},
  author = {Park, R. and Epstein, S.},
  date = {1960-12},
  journaltitle = {Geochimica et Cosmochimica Acta},
  shortjournal = {Geochimica et Cosmochimica Acta},
  volume = {21},
  number = {1-2},
  pages = {110--126},
  issn = {00167037},
  urldate = {2023-08-13},
  langid = {english}
}

@article{park1961,
  title = {Metabolic fractionation of $\mathrm{C}^13$ \& $\mathrm{C}^12$ in plants},
  author = {Park, Roderic and Epstein, Samuel},
  date = {1961-03-01},
  journaltitle = {Plant Physiology},
  shortjournal = {Plant Physiol.},
  volume = {36},
  number = {2},
  pages = {133-138},
  issn = {0032-0889, 1532-2548},
  doi = {10.1104/pp.36.2.133},
  urldate = {2023-08-13},
  langid = {english},
}

\end{filecontents}
\documentclass{article}
\usepackage[backend=biber,style=gb7714-2015ay,gblabelref=true]{biblatex}
\addbibresource{test.bib}
\usepackage{ctex}
\begin{document}
第一段测试：\citet{park1960, park1961}。\par
第二段测试：\citep{park1960, park1961}
\end{document}

输出为：

我应该怎么做才可以使得输出为：

Part et al. (1960, 1961).
(Part et al., 1960, 1961)

谢谢。
