How to add publisher to biblatex style (fiwi)?

I am using biblatex with biblatex-fiwi and the fiwi2 option:
\usepackage[
backend=biber,
style=fiwi2,
]{biblatex}
I am super content with the style, just publishers are omitted in the bibliography.
I would love to see the publisher added at the end (Sage manually entered, bold)
Hofstede, Geert (2003): Culture’s Consequences: Comparing Values, Behaviors, Institutions
and Organizations Across Nations. 2. Aufl. Sage
How to get the publisher, which is in the *.bib file, into this bibliography?
