help with uni cpo woocommerce plugin

sorry for my english ... I created this product [login to view URL] see attached pdf It's working pretty well but there are 4 things that are not done: 1) quantity discounts 2-4 books: 5% discount 5-9 books: 10% discount 10-19 books: 15% discount more than 20 books: 20% discount The discount should be applied on the product page if possible. If not, it could also be applied in a cart 2) Delivery time 7 days: no surcharge 4 days: fixed surcharge of € 3.2 on total order + 10% on the cost of the order 2 days: fixed surcharge of € 5 on total order + 20% on the cost of the order 3) I prefer to use the "quantity" field by default of woocommerce. it's possible? 4) I prefer to put the price of the options within the options and not in the formula, is it possible? I do not get it.... I'm really migrating this product, it has to be the same [login to view URL] for the moment that's it, surely need more things for this and other websites that I want to migrate to uni cpo thank you
