Previously, there was no option to specify which plan or group a coupon applied to during its creation. With the filter of One-time Coupons, users can now assign coupons to specific plans and groups individually, allowing for better control and customization of discount applications.

Steps to create a coupon with specific eligible plans/groups:

1. Log in to your AT dashboard.
2. Go to Configure → Coupons.
3. Click on Add Coupon.
4. Under Eligible Plans, first select the desired Group from the dropdown.
5. Choose the required Plan under that group.
6. Click Save.
