Thanks for the suggestion, Fraser.
Breww’s location positioning is a lot more advanced than just the postcode, but that doesn’t mean it will always be able to find the perfect spot. Sadly, address geolocation is far from an exact science.
We plan to do what you’re asking for (allowing setting a specific pin spot) as part of Custom pins for delivery locations (e.g. parking spot, correct door for entry, etc). Could you give that thread a vote?
If you don’t think that covers what you need, please let me know. Cheers.
