Feature request: Coupon code tracking

Hi there!

It would be great to have you add your ideas to the Ideas Board -(https://ideas.woocommerce.com/forums/133476-woocommerce?category_id=337630), which is where developers go to look for future plugin features and improvements.

You can also vote for other posts if you agree with their idea. This is especially important if you see a similar idea as yours, in order to avoid duplicates.
