Fixtures.create_fixtures with any desired filenames?

Hi all

I’d like to create fixtures using


But it seems that this one needs .yml files that have the same name like
the table they correspond to:

countries.yml => my_db.countries
readers.yml => my_db.readers

Is it possible to use any desired filenames somehow?

some_cool_countries.yml => my_db.countries
some_other_cool_countries.yml => my_db.countries

Thanks for any help,
