I use \footfullcite{ref1,ref2} from the biblatex package to obtain a single footnote for multiple citations and I need to reference to that same footnote later in the document.
My current hacky way of doing this is the following
\footfullcite[\hspace{-.22em}\protect\label{refgroup}][]{ref1,ref2}
the use of \protect is fundamental, as I learnt here and when I want to add a second reference to the same footnote I use \footref{refgroup} (using the KOMA script functionality as explained in this answer).
As you can see, I need to manually add some negative horizontal space, because putting the label in the the <prenote> field of \footfullcite adds an some empty space (putting it in the <postnote> field ends the footnote with a comma instead of a full stop, so it's even worse).
Does anybody have any suggestions on how to achieve the same goal more elegantly? This question poses a similar problem, but the code suggested there does not show multiple citations in the same footnote.
\AtNextCitemay work for that label. – gusbrs Oct 02 '21 at 13:46\AtNextCite{\label{refgroup}}\footfullcite{ref1,ref2}does not work as intended, but maybe you had in mind something different. – justmyfault Oct 02 '21 at 15:20fullciteand create the footnote manually, i.e.\footnote{\fullcite{ref1,ref2}.\label{refgroup}}. I guess I'll just create a macro for this. – justmyfault Oct 02 '21 at 15:22\footcitewould be\footnote{\cite{ref1,ref2}}I believe. – gusbrs Oct 02 '21 at 18:39
