如何使用 footcite 获取多个引用条目？

Question

我正在使用 Biblatex 将参考文献放入脚注中。以前我使用 \cite{} 插入参考文献时，只需用逗号分隔参考文献即可放入多个参考文献：\cite{ref1, ref2} 会导致 blah blah blah [1,2]；而 \cite{c1,c2,c3} 会导致 [1-3]

我尝试使用 \autocite，但似乎不起作用。有没有简单的方法可以让它工作？

以下是一个例子：

\documentclass{article}
\usepackage[style=verbose,backend=bibtex, autocite=footnote]{biblatex}

\begin{filecontents*}{bibliography.bib}
    @article{c1,
    author = {Neil, Daniel and Liu, Shih-Chii},
    journal = {IEEE Transactions on VLSI Systems},
    title = {{Minitaur, an Event-Driven FPGA-Based Spiking Network Accelerator}},
    year = {2014}
    }

    @book{c2,
      title={Event-Based Neuromorphic Systems},
      author={Liu, Shih-Chii and others},
      year={2015},
      publisher={John Wiley \& Sons}
    }
    @inproceedings{c3,
    title = {Personalized Speech Recognition On Mobile Devices},
    author  = {Ian McGraw and others},
    year  = 2016,
    booktitle = {ICASSP}
    }
\end{filecontents*}

\bibliography{bibliography.bib}

\begin{document}
I would like the footnote citations~\autocites{c1,c2,c3} to look $like^{1-3}$, but I got 1. 
\end{document}
