Ich würde die Fussnoten gerne mit einem Komma trennen, wenn mehrere zusammen vorkommen. Habe es mit
\autocite{key,key} bzw.
\autocite{key}\autocite{key} bzw.
\autocite{key}~\autocite{key}
probiert, doch es kam nicht das gewünschte Ergebnis raus. Ein Komma zwischen den Fussnoten fände ich eleganter als einfach nur ein Abstand.
Kann mir da jemand behilflich sein?
