Multiple footnotes within a mdframed to refer to the same text

Question

I am using an mdframed to a display large list of items. In this this list, there is one exception that a few of the items have, and I am trying to make a note of this via a footnote. The text of the footnote is the same for all the exceptions. So what I would like is:

• Multiple footnotes using the same symbol (in each mdframed)
• Each of the footnotes to link to the one piece of text at the end of each mdframed

I tried the hack below based on Making global footnotes inside a minipage with hyperref support, which gets me the same symbol for the footnote, but only the last footnote is properly linked.

Notes:

• If at all possible I would prefer to not have to do multiple runs. Since one instant of the footnote does not require multiple runs I think this should be doable without that.

Add \addtocounter{Hfootnote}{-1}% additionally.

\documentclass{article}
\usepackage{mdframed}
\usepackage{lipsum}
\usepackage{xcolor}

\usepackage[colorlinks=true]{hyperref}

\makeatletter

\newcommand*{\MyFootnoteMark}{%
    \footnotemark%
%   \global\let\saved@Href@A\Hy@footnote@currentHref%
    \addtocounter{footnote}{-1}%
    \addtocounter{Hfootnote}{-1}%     Added
}%

\newcommand*{\MyFootnoteText}[1]{%
%%  \addtocounter{footnote}{-1}%
%   \let\Hy@footnote@currentHref\saved@Href@A%
    \footnotetext{#1}%

Another ugly hack to bring back the symbols in the footnote

\documentclass{article}
\usepackage{mdframed,footnote}
\usepackage{lipsum}
\usepackage{xcolor}
\usepackage{xparse}

\usepackage[colorlinks=true]{hyperref}

\makeatletter
%% Adapted from http://tex.stackexchange.com/questions/119092/making-global-footnotes-inside-a-minipage-with-hyperref-support
\newcommand*{\MyFootnoteMark}{%
    \footnotemark%
    \addtocounter{footnote}{-1}%
    \addtocounter{Hfootnote}{-1}%     Added
}%

\newcommand{\MyFootnoteText}[1]{%
    \footnotetext[\numexpr\value{footnote}+1\relax]{#1}%
    \refstepcounter{footnote}%
    \refstepcounter{Hfootnote}%      %% Added
}%
\makeatother

\def\@fnsymbol#1{\ensuremath{\ifcase#1\or \dagger\or \ddagger\or
   \mathsection\or \mathparagraph\or \|\or **\or \dagger\dagger
   \or \ddagger\ddagger \else\@ctrerr\fi}}%
\renewcommand\thefootnote{\fnsymbol{footnote}}
\renewcommand\thempfootnote{\fnsymbol{mpfootnote}}
\makeatother

\NewDocumentCommand{\MyContent}{O{yellow!20}O{}}{%

\begin{minipage}{\linewidth}\color{blue}
Hey, look at me.\MyFootnoteMark
\end{minipage}%
\par\lipsum[2]
\begin{minipage}{\linewidth}\color{blue}
