Here's an untested sketch:
------------------------------------------------------------------------
class mywrapper(ofx.Importer):
def extract(self, file, existing_entries=None):
entries = super().extract(file, existing_entries)
return list(map(categorize_entry, entries))
------------------------------------------------------------------------
where categorize_entry is your function that takes an input an entry and
returns an improved version of it. (Note that due to the extract
interface your function should really handle all possible Beancount
entries, not only transactions. Presumably you'll return all other
entries unchanged.)
Let me know if it works :-)
Cheers
