I'm using biblatex with the autocite=superscript option, so I can use \autocite to switch the interpunction and a superscript citation when the \autocite command is placed before an period or comma. I'd like to move the citation closer to or above the interpunction.
What I want to achieve is shown at the second half of the page: http://www.khirevich.com/latex/footnote_citation/
The solution given on the page consist of a new command that takes both the citation as well as the interpunction as an argument:
\newcommand{\sjcitep}[2][]{% new command with two arguments: optional (#1) and mandatory (#2)
\settowidth{\spc}{#1}% set value of \spc variable to the width of #1 argument
\addtolength{\spc}{-1.8\spc}% subtract from \spc about two (1.8) of its values making its magnitude negative
#1% print the optional argument
\hspace*{\spc}% print an additional negative spacing stored in \spc after #1
\supershortnotecite{#2}}% print (cite) the mandatory argument
Is it possible to change the \autocite command such that it inserts a \hspace like in the code above between the interpunction and the superscript whenever it puts the superscript behind an interpunction character?

\citecommand, this slightly different adaptation works:\AdaptNoteOpt\cite\multautocite.
