Need revision with rounding off the price of goods with a discount

It is required that the prices of goods are always integers. Even after applying the discount. Therefore, it is necessary that the rounded price be transmitted in the checkbox when the option "Transmit position price including discount" is enabled. With this option, the price is transferred from the field Total price (productpricediscount)? The rounding setting in the action itself is not suitable, because in the process, the amount must also be rounded and fully correspond. TK: You need a setting to round the price of the Total price (productpricediscount) field according to mathematical rules to integers (1-4 downwards, 5-9 upwards). Rounding is needed not in all BPs, but only in certain ones, so you need an option with a BP selection if the setting is moved to the Business Process Builder settings, or display this setting in the Product Table (how easier/cheaper?).
