(WOOCOMMERCE) Exclude product from dynamic price bulk selling. -- 2

i have a webpage that are basicaly a bulk selling ecommerce. but now i like to sell some products without that dynamic pricing ( in base of the amount of the order ). So, i need some checkbox in the admin or something else, so, if the client buy in bulk and some product without bulk price, the amount of this last product (not bulk) dont interfer on the dynamic price of the order. For example $5000 you get some discount $10000 you get more discount $20000 you get more discount but i like some items dont be included into this dynamic price My website: [login to view URL]
