Hi,
There is no such feature in HikaShop.
There is a global counter when you see the details for a coupon but there is statistic or counter on a particular time frame.
I guess I can add it in our TODO list but without more description I'm not sure it will be approved ; it is too vague.
On the other side you can add it using a view override or custom plugins. It requires some development/PHP skills but it is possible.
