Odoo Community: Multiple Companies with Shared Products

Hi, I have three companies using the same database, and I want a shared or master list of products for all three. We migrated the product data without specifying a company branch name, and it was successful. However, I noticed that two of the companies don't have the unit prices, while one does. Is it possible to have shared products with different quantity levels for each plant?

The reason I want shared products across the three companies is to maintain consistent details and product names, ensuring a centralized and unified system.
