Pricing based on product size without setting up each product?

[rtnlsltn]

Is there a way to set up pricing based upon product size in Prestashop without selecting each increased measurement/price option for each product? All of my products are dependent on size, I'd like to make this default or easier to add into "Combinations" than checking each one when adding. Right now, I've got to add "12x18" then "6x9" and so on, for every product I add through the "Combinations" screen.

Thanks!

up up up, anyone?

Also, is it possible to charge based on a user entered value?

EX: charge by square inch ($1), user enters 10 x 10, charge $100

No, it is impossible to charge based on a user-entered value in PrestaShop. The best you can do is add a text field where the customer can enter their square inches, but you'd have to manually calculate the price after receiving the order and ask the customer to pay.

The best way is to use attributes like you are doing. To get around entering the same combinations manually for each product, I suggest using the Attribute Order module, which lets you copy attributes from one product to another or to an entire category.
