从 biblatex 文本引用中删除“and”

Question

自 2.7 版起，在文本引文字符串的最后一个引文前biblatex添加该单词and。这很不错，但这种一刀切的行为并不总是合适的，如下例所示。

and问题是，当我知道不合适时，我怎样才能抑制添加？

\addbibresource{\jobname.bib}
\begin{document}
You can find a lot of interesting material on the Beatles,
such as \textcites{lennon1972}{lennon1974}{mccartney1975},
the never published manuscript by \citeauthor{harrisonms},
and finally Ringo Starr's autobiography \parencite{starr1985}.

Answer 1

\AtNextCite{\renewcommand*{\textcitedelim}{\addcomma\space}}在相应的引用前添加。
