[Tex/LaTex] Subfigure vertical alignment

Question

I have several subfigures in a figure. There is one image that has a much lower vertical width than the others and it is placed at the bottom of the subfigure region. Also the caption is placed below both figures(I have a nx2 grid). How can I align/center a subfigure vertically with respect to the others and how can I get the caption to apply only the subfigure it is in?

But I would like

Answer 1

Perhaps something like this.

\documentclass{article}
\usepackage{graphicx}
\usepackage[export]{adjustbox}
\begin{document}
\begin{figure}
\includegraphics[width=.4\linewidth,valign=c]{example-image-10x16} %valign key is from adjustbox
\begin{minipage}{.5\linewidth}
\centering
\includegraphics[width=.8\linewidth]{example-image}
\caption{Bla bla}
\end{minipage}
\end{figure}
\end{document}
