[Tex/LaTex] Latex “element of with two strokes” (⋹)

Question

Is there a latex symbol akin to \in, but with two strokes? It has a Unicode equivalent, ⋹. I looked on detexify, but I couldn't find anything that matched. If it doesn't exist, how might I "rig" it?

Edit

The solutions posted do work, but I also now find the need to have a MathJax version of the symbol. I am not sure as to how to include the solutions given in a MathJax define key; using the usual "macros" produces an error.

Here's one option using \ooalign:

\documentclass{article}
\usepackage{graphicx}
\usepackage{amsmath}

\newcommand\Inn{%
  \mathrel{\ooalign{$\subset$\cr\hfil\scalebox{0.8}[1]{$=$}\hfil\cr}}%
}
\begin{document}

\[
A\in B
\]

\[
A\Inn B
\]

\end{document}

The result:

And if you need it for the different math styles:

\documentclass{article}
\usepackage{graphicx}
\usepackage{amsmath}

\newcommand\Inn{%
  \mathrel{\mathchoice
    {\ooalign{$\displaystyle\subset$\cr\hfil\scalebox{0.8}[1]{$=$}\hfil\cr}}%
    {\ooalign{$\textstyle\subset$\cr\hfil\scalebox{0.8}[1]{$\textstyle=$}\hfil\cr}}%
    {\ooalign{$\scriptstyle\subset$\cr\hfil\scalebox{0.8}[1]{$\scriptstyle=$}\hfil\cr}}%
    {\ooalign{$\scriptscriptstyle\subset$\cr\hfil\scalebox{0.8}[1]{$\scriptscriptstyle=$}\hfil\cr}}%
    }%
}

\begin{document}

\[
A\in B\quad{\textstyle A\in B}\quad  L_{A\in B}\quad  M_{L_{A\in B}}
\]

\[
A\Inn B\quad{\textstyle A\Inn B}\quad  L_{A\Inn B}\quad M_{L_{A\Inn B}}
\]

\end{document}
