Back references for shorthandlist

Question

I am using biblatex for writing my thesis and it works generally fine. Now I want to put back references to my bibliography. However, after putting the option into the preamble, the back references only appear in the normal bibliography but not in the list of the shorthands. Does anyone know how to make the shorthand list including the back references? Here is a mini example (compiled with lualatex, but I think the result is the same as with latex):

\documentclass{memoir}
\usepackage{filecontents}
\begin{filecontents*}{mybib.bib}

@book{Abook,
author = {First Author and The Second Author},
title = {The Longtitle and not the Shorttitle},
shorthand = {LnS},
publisher = {The Publisher},
address =  {Address},
year = {1965}}

@article{Aarticle,
author = {Article Author},
journal = {Journal Title},
pages = {113-126},
title = {Title of the Article},
volume = {65},
year = {1968}}

\end{filecontents*}
\usepackage[hidelinks]{hyperref}
\usepackage[style=philosophy-modern,backref=true,hyperref=true,language=auto,autocite=inline]{biblatex}

\defbibcheck{noshorthand}{%
\iffieldundef{shorthand}{}{\skipentry}}

\bibliography{mybib}
\bibintoc
\usepackage[ngerman,english]{babel}%english names of sections
\usepackage[babel,english=british]{csquotes}

\begin{document}
Backreference?
\cite{Abook}
\cite{Aarticle}
\printshorthands
\printbibliography[check=noshorthand]
\end{document}

Result:

Answer 1

Modifying the shorthands bibliography driver seems to do the trick.

\documentclass{memoir}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}

@book{Abook,
author = {First Author and The Second Author},
title = {The Longtitle and not the Shorttitle},
shorthand = {LnS},
publisher = {The Publisher},
address =  {Address},
year = {1965}}

@article{Aarticle,
author = {Article Author},
journal = {Journal Title},
pages = {113-126},
title = {Title of the Article},
volume = {65},
year = {1968}}

\end{filecontents*}
\usepackage[hidelinks]{hyperref}
\usepackage[style=philosophy-modern,backref=true,hyperref=true,language=auto,autocite=inline]{biblatex}

\defbibcheck{noshorthand}{%
\iffieldundef{shorthand}{}{\skipentry}}

\addbibresource{\jobname.bib}
\bibintoc
\usepackage[ngerman,english]{babel}%english names of sections
\usepackage[babel,english=british]{csquotes}

\DeclareBibliographyDriver{shorthands}{%
  \usedriver
    {\DeclareNameAlias{sortname}{default}}
    {\thefield{entrytype}}%
  \setunit{\bibpagerefpunct}\newblock% NEW
  \usebibmacro{pageref}% NEW
  \finentry}
