Скидка на заказ, зависящая от платежной системы

Добрый день, подскажите пож-та можно ли стандартными инструментами Битрикс сделать скидку зависящую от платежной системы не фиксированной а в процентном соотношении, т.е если я как пользователь добавляют товар в корзину и перехожу на форму оформления заказа нужно считать процент от моей стоимости если я выбрал определенную платежку, сейчас только фикс.[img]data:image/png;base64,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
