如何使用子图将文本置于图中中央

假设我有这样的代码：

\documentclass[12pt,a4paper]{article}
\usepackage{graphicx}
\usepackage{subfig}

\begin{document}

\begin{figure}
\textbf{Text I want centered} \\
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}} \hfill
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}}  \hfill
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}} \\
{\centering \textbf{Text to be centered}} \\
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}}  \hfill
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}}  \hfill
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}} \\
{\centering \textbf{Center me}} \\
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}}  \hfill
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}}  \hfill
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}} \\
\end{figure}

\end{document}

我的目标是将文本置于每组三个数字的上方。第一个不起作用，因为我没有尝试将其居中。但是，我预计第二个和第三个会居中，因为我将它们放在{\centering }代码片段中。有没有办法将它们居中？如果有更好的方法（例如副标题或其他内容），则不需要对文本进行编码。

\documentclass[12pt,a4paper]{article}
\usepackage{graphicx}
\usepackage{subfig}

\begin{document}

\begin{figure}
\centering
\textbf{Text I want centered}

\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}} \hfill
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}}  \hfill
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}}

\textbf{Text to be centered}

\textbf{Center me}

\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}}  \hfill
\subfloat[Image]{\label{}\includegraphics[width=42mm]{example-grid-100x100pt}}  \hfill
