Modification of price calculation at configurator for store on idosell engine

I will commission a modification in an idosell-based online store.

Namely, it currently works like this:

The system currently calculates prices for the product ( price per item + additional price from the configurator)* number of items and only from this is the discount given.

On the other hand, we need the quantity discount to be given only on the price per product, not the sum of the prices of the product and the configurator add-on.

The second topic, which is we need a modification of the configurator so that the price on the card in the cart takes into account the quantity discount immediately, and not after adding to the cart
