Prices in multistore

[StIvSZ]

Hello, I am working on Prestashop 1.7.8 I work with multistore. I have 9 stores in the multistore, which are divided into 2 groups. Many of the products are visible in all stores, but some are only visible in some stores. I have a main store in which absolutely all stores are visible. I've made this store get real-time product prices and availability from my suppliers. Prices and availability change for the main store, but how can I make other stores show the same price and availability?

Main Store -> Price 1 -> Availability 1
Store 2 -> Price 1 -> Availability 1
Store 3 -> Price 1 -> Availability 1
Store 4 -> Price 1 -> Availability 1
Store 5 -> Price 1 -> Availability 1
Store 6 -> Price 1 -> Availability 1
