Cashback not update after adding a new products in customer order

Hello!
I have a big shop on wordpress and I use your cashback system. I test this plugin for a long time and I can’t find some important functions.

1. In my shop manager often add new products in customer order by the phone conversation. And in this way cashback disregard this new products. So operator can add a cashback only manually.

2. Except cashback I have a discount system in my shop. Now cashback counted from original order amount. For example, order price is $100. I gave 5% discount. Now order price is $95. Cashback amount counted from $100, not $95. I need that cashback amount counted after apply discount and pay by woowallet. I mean that cashback counted from amount that customer payed.

3. When order status changed on “canceled” cashback amount does not return automatically on wallet. Manager doing it manually. Again. If he forget to do it we get an unpleasant situation.

Maybe you plan to add this functions in nearest future? Especially the 1st point is very important because in many online-shops managers are sell additional products by phone.

Thank you!
