I have supplied over 15,000 examples of records in NationBuilder where the autodistricting has failed. In all of these cases the records had a valid postal code in the registered address field, so it should have been possible to correctly autodistrict them. When I try to upload the correct electoral districts via bulk import or the API, the autodistricting overwrites the correct values, with incorrect values or blanks the fields. It would be really helpful if autodistricting could be controlled on a record-by record basis. This would mean that when I knew the correct electoral districts for a record I would be able to upload them (via and import file or the API), while still benefiting from autodistricting for other records.
