Price Variations

[CreativeDesigns]

I hope someone can help.
My client needs product price variations. Essentially each product is a different height, and each height costs more than the last.

On the system, from what I can see with the cart variations is that a base price needs to be set for the main product, and then each variation would add on an extra amount.
Is there no way to have the dropdown menu be the full price of the product, as opposed to extra money being added to the original product? I think this would confuse clients.
