Coupon codes import

Hello there,
first of all, thank you for creating such a useful tool.

I’m wondering where I can manage and import the coupons.
I already created on a previous website a number of codes and I necessarily need them to be imported in the new website.

At the same time, in the “coupons” tab I see that there are the coupons because the number next to “all” and “mine”, but they are not showing, I get a contradictory “no coupons found” message.

Thank you so much for your support
