cocart apply coupon response breakdown

Hello,

I’m using the following coCart API to apply a coupon “A15”

POST {{API_URL}}/cocart/v1/coupon?cart_key=<cart_key>

“A15” is configured to provide a 15% discount and have a limit of 3 items. When the coupon is applied to a cart that contains a single product “P1” with quantity 5, the discount got applied to 3 items and the other 2 items are charged full price. Following is a sample request & response of GET cart API after coupon is applied

GET {{API_URL}}/cocart/v2/cart?lang=en&cart_key=<cart_key>

      "Coupon code applied successfully."
    ]
  }
}

The original price of “P1” is 299. After applying the coupon to the cart of 5 items, the above response returned a total of “1360.45”. If you do the math you’ll understand that the discount was applied to 3 items & 2 items got charged full price.

Is there any way to have the GET cart response indicate that the discount got applied to 3 items and 2 items charged full price?
