Añadir Shorttitle al final de la entrada en la bibliografía

Question

Estoy intentando agregar un título corto (u otro campo como usuario) al final de la bibliografía.

Aquí mi MWE:

\documentclass[
    12pt,
    oneside
]{scrartcl}

\usepackage[
    backend=biber, 
    style=ext-authoryear,
    firstinits=false
]{biblatex}

\addbibresource{test.bib}

\begin{document}
    \section{Test}
    \cite{author01}
    \cite{author02}
    \printbibliography[]
\end{document}

Y el babero:

@book{author01,
 author = {John, Doe},
 year = {2015},
 title = {How to use BibLaTex the wrong way},
 edition = {12},
 publisher = {{Catoso}},
 subtitle = {BibLaTex for Dummys},
 location = {Denmark},
 shorttitle = {Biblatex wrong way}
}

@article{author02,
 author = {Mary, Doe},
 year = {2015},
 title = {How to use BibLaTex the right way},
 edition = {12},
 publisher = {{Catoso}},
 subtitle = {BibLaTex (not) for Dummys},
 location = {Denmark},
 pages = {835--854},
 shorttitle = {Biblatex right way}
}

Sin:

¿Es posible colocar el título corto en el último lugar de la entrada? ¿Tiene alguna idea de cómo lograrlo? ¡Gracias!

Saludos cordiales, Marc

Con los estilos estándar y la mayoría de los estilos de terceros, puede redefinir bibmacro finentrypara agregar algo al final de una entrada de bibliografía.

\documentclass[
    12pt,
    oneside
]{scrartcl}

\usepackage[
    backend=biber, 
    style=ext-authoryear,
    firstinits=false
]{biblatex}

\DeclareFieldFormat{bibshorttitle}{\mkbibbrackets{#1}}
\renewbibmacro*{finentry}{%
  \setunit{\addcomma\space}%
  \printfield[bibshorttitle]{shorttitle}%
  \finentry}

\begin{filecontents}{\jobname.bib}
@book{author01,
 author = {John, Doe},
 year = {2015},
 title = {How to use BibLaTex the wrong way},
 edition = {12},
 publisher = {{Catoso}},
 subtitle = {BibLaTex for Dummys},
 location = {Denmark},
 shorttitle = {Biblatex wrong way}
}
@book{author02,
 author = {Mary, Doe},
 year = {2015},
 title = {How to use BibLaTex the right way},
 edition = {12},
 publisher = {{Catoso}},
 subtitle = {BibLaTex (not) for Dummys},
 location = {Denmark},
 pages = {835--854},
 shorttitle = {Biblatex right way}
}
\end{filecontents}
\addbibresource{\jobname.bib}

\begin{document}
    \section{Test}
    \cite{author01}
    \cite{author02}
    \printbibliography[]
\end{document}
