Using biblatex in combination with the apa style, I would like to cite references with institutional authors. As suggested in a previous post I use the shortauthor field to include abbreviations.
My issue occurs with references that include multiple institutional authors. Here I would like to use multiple entries in shortauthor as well. But the output I get looks not at all as expected.
Example:
\documentclass{article}
\usepackage{filecontents}
\begin{filecontents}{references.bib}
@BOOK{ACER2015,
author = {{Agency for the Cooperation of Energy Regulators} and {Council of European Energy Regulators}},
shortauthor = {{ACER} and {CEER}},
title = {{ACER/CEER} Annual Report},
year = {2015}
}
@TECHREPORT{CEER2014,
author = {{Council of European Energy Regulators}},
shortauthor = {{CEER}},
title = {{CEER} Advice},
year = {2014}
}
\end{filecontents}
\usepackage[backref=false,style=apa,backend=biber]{biblatex}
\addbibresource{references.bib}
\begin{document}
First reference produces output with unexpected format \parencite{ACER2015}.
Second reference looks correct \parencite{ACER2015}.
A third reference to one of the previous authors produces full output \parencite{CEER2014}.
\end{document}
This produces the following output:

The expected output would have been:

How can I make use of the shortauthor field to achieve the expected outcome?
