Price Attributes

Hi: I am working with woocommerce attributes and the client is adding variable products (attributes). He has a lots of combinations (for example 5 sizes with 6 colors, which leads to 30 possible combinations). He wants to manage stock on those 30 combinations, but have the same price and image. Is the re a way to just change stock, but do not have to set price+image one by one on the variations which is time wasting?
Pls let me know, thks…
