I'd need to create price rules for an unique customer, like:
For certain products:
General: 0% discount Retailer: 5% discount Wholesale: 10% discount Customer1: 20% discount Customer2: 22% discount Customer3: 15% discount etc.
I know you can do a group customer for an unique customer, but I think I will work better having directly the option to add price rule for a certain customer.
I thought about adding another field below Customer groups: "Customers" And could add ID customer inside the field.
But I have no idea how to begin, you think it will be a nightmare?
