The system wasn't made to be easy to configure for such cases but to allow a maximum of flexibility so that you could set different prices for all the combinations you have.
In the business edition, you have a copy button on the listing of products so that would help you set all your products: you do it once for a product and then you can just copy the product and modify the different information in the new product. Also, you can use the import screen to import all your prices from a CSV at once.
