Is there are a way to know from where a sale comes from? I'm particularly interested in sales I made(with my promo code). On the sales report, I can see all the sales and what coupon code they used but can't find which was the source of that(e.g. Facebook, Twitter, medium articles, etc.).
This would be very useful, because I can know that I made, let say, 10 sales from a FB post, or 5 sales from an article I wrote, etc.
As far as I can see it's not possible, but it would be very helpful to know.
