Link text and figures including subplots

Question

I have a figure with many subplots created and labeled in Matlab. In the text of the tex file, I need to refer to each subplot separately e.g. 1a) 1b)..., nevertheless I can obviously link only the entire figure e.g. 1 in the text. How can I include the letters in the link? So far I have only changed the color of the letters manually, but I would also like to have the link if I go with the cursor above the letter.

For example I have a figure with three subplots and I need to discuss the first one:

\documentclass[%
reprint,
superscriptaddress,
amsmath,amssymb,
aps,
prb,
]{revtex4-2}

\hypersetup{
        colorlinks   = true,
        citecolor    = blue,
        linkcolor    = blue}

\begin{document} 


\begin{figure}[t]
 \centering
 \includegraphics[width=1\textwidth]{img.eps}
 \caption{(a) subplot1 (b) subplot2  (c) subplot3}
 \label{fig:figure}
 \end{figure}

Figure \ref{fig:figure}{\color{blue}{(a)}

\end{document}

Thank you!
