Increase spacing between entries in LOT and LOF

Question

I am modifying a thesis template to satisfy the format requirements of my school. They ask for a single-line spacing within a entry in 'LoT/LoF', but require an extra line spacing between each entry. Something like (for example 'Figure 1.1's name is more than 1 line):

               List of Figures
1.1 aaa  
aaaa    

1.2 bbb    

1.3 ccc

I looked into the .cls-file and changed the line spacing format for 'LoT/LoF' to be single-lined spacing. But I do not know how to increase the spacing between each entry. Right now, my file looks like

Here is some related MWE I have (I paste the whole unmeethesis.cls file here: http://pastebin.com/i2NfxHUf. Also need to create a file called unm12.clo to compile this, which is in the comment (I cannot add two links as a new user to the community)) :

\documentclass[botnum, fleqn]{unmeethesis}


\begin{document}
\clearpage
\setcounter{page}{1}%
\pagenumbering{roman}
\tableofcontents
\listoftables
\listoffigures
\mainmatter
\chapter{AAA}
\section{aaa}
\begin{table*}[!ht]
\caption{Sample Table 1, a very very very very  looooooooooong name for example}
\end{table*}

\begin{table*}[!ht]
\caption{Sample Table 2}
\end{table*}
\section{bbb}

\chapter{BBB}
\section{aaa}
\section{bbb}

\end{document}

Answer 1

Would something like this solve your question?

\documentclass[botnum, fleqn]{unmeethesis}

\begin{document}
\clearpage
\setcounter{page}{1}%
\pagenumbering{roman}
\tableofcontents
{
\setlength{\parskip}{20pt}
\listoftables
}
\listoffigures
\mainmatter
\chapter{AAA}
\section{aaa}
\begin{table*}[!ht]
\caption{Sample Table 1, a very very very very  looooooooooong name for example}
\end{table*}

\begin{table*}[!ht]
\caption{Sample Table 2}
\end{table*}
\section{bbb}

\chapter{BBB}
\section{aaa}
\section{bbb}

\end{document}
