referencing to citation in a refsection

Question

Is it possible to reference to a citation inside a refsection from the outside? And I mean outside not as in "inside another refsection", but as in "inside no refsection".

In the following MWE, the label of ArticleA is properly printed, but the link does not lead to the list of references in SectionB.

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents}{MWE.bib}
@article{articleA,
author = {Clark Kent},
title  = {On why superman is stronger than batman},
journal = {The daily planet},
year   = {2016},
}
@article{articleB,
author = {Bruce Wayne},
title  = {On why batman is stronger than superman},
journal = {Wayne Enterprises journal},
year   = {2016},
keywords = {blablabla},
}
\end{filecontents}
\usepackage[backend=biber,style=alphabetic]{biblatex}
\addbibresource{MWE.bib}
\usepackage[colorlinks]{hyperref}
\hypersetup{urlcolor=blue, citecolor=blue, linkcolor=blue}

\begin{document}

\section{Section Title A}
This is outside any refsection.
Here's a normal reference: \cite{articleB}. 
Here's a reference that's only listed inside a refsection: \cite{articleA}
\printbibliography[keyword=blablabla]

\newpage
\begin{refsection}
\section{Section Title B}
\cite{articleA}, \cite{articleB}
\printbibliography
\end{refsection}

\end{document}

Answer 1

You probably want to use refsegments instead of refsections. Since the latter keep all their contents local there is no way to access it from the outside. The content of refsegments can be easily accessed from the outside, though.

What you have to keep in mind is that \printbibliography does not automatically restrict itself to the current refsegment, you will have to do that manually with

\printbibliography[segment=\therefsegment]

Note also that disambiguation features are applied across refsegments, while refsections keep the disambiguation local.
