Copy characteristics, variants and prices

This is my situation:

I have 50 images, all are printed on demand in different sizes.
Example: Image A can be ordered in size 1 - price = 50, size 2 = price 60, size x = price x (15 possible sizes), the same with size B

So the product is an image and people can order, thanks to characteristics, their prefered size.
So I used characteristics Size and entered the 15 sizes, then I went to the product, added the characteristic and entered a price for every size.

Is there a possiblity to copy these so I can automatically add all these prices to every product in the category? Or do I have to manually add them for each single product?

Hi,

If you only use the variants, you will have to set it for each single product.
But you can use the "options", create an option product like "size" and add the characteristic to this product, manage the vairants, set the desired price.
And in each single product, add the option product.
