Custom Pricing Based on Page Count Range in Medusa Dashboard and Frontend Integration

[TADENIZ20]

I would like to modify the backend in the Medusa Dashboard to handle a product option called "Page Count". Instead of manually setting a price for every possible number of pages, I want to create a price range. For example, 1-100 pages would cost 20 cents, 101-200 would cost 15 cents, and so on. Then, in the frontend, I want to create an input field where the customer can type, for example, 87 pages, and the backend will return the price for the range 1-100. I can handle the frontend input field, but modifying the backend in the dashboard is overwhelming. Can someone help me? I am using the default installation with npx create-medusa-app@latest. with fronted and dashboard
