How to create agregated stat
We use coupon codes on our website, and wometimes people do not spell them right. For instance, the code "Welcome" is spelled : welcome or WELCOME, or Welcome,,...
What I would like to do is to create one new stat that regroups several items. For example, create a new stat called "Welcome" that gives me all the used coupons associated, only in 1 line in my tab
WELCOME = 45
Welcome = 10
welcome = 5
I would have a new tab with only one line:
Welcome = 60
How can I do so ?
