Hi thanks everyone for the feedback! With it I managed to use the %(expression) in org-agenda-prefix-format to show the breadcrumbs. In case that's useful for other people too, I attached a patch that adds a %b option to org-agenda-prefix-format to does the same. Would be great, if this could be included.
Thanks Arun
