It is possible to make coupon codes with the condition of 'customer username' so it would be extremely beneficial to be able to bulk import a list of customers and individual/unique codes via CSV.
Currently, if I have 100 customers in QLD that I wish to offer an individual, limited time, single use coupon code to, I would have to manually create 100 codes which could take hours. By providing an option to import import one CSV file this could be done in minutes.
This would be useful in a variety of promotion scenarios.
