Figure titles on the list of figures

[IChi Lai]

Hello,

I have a question regarding the presentation of the list of figure. Each of my figure captions includes its title and the description. Right now they are both included after the "\caption", but I was wondering if there's a way to separate the title and the description so that on the list of figures/list of tables, I can show the title only, but in the caption right below the figure, I can show both of the title and description in the caption. Please let me know if this question is clear enough, and how I can go about modifying the code. Below is the code I have been using just in case:

\begin{figure}

    \centering

        \includegraphics[width=0.9\textwidth]{images/image1.pdf}

        \caption{\textbf{Figure Title} Figure description.}

        \label{fig:img1}

\end{figure}

Thank you!
