Connect calculated price to webflow card and checkout

Hey everyone,

i have webflow ecommerce. I have integrated a calculator on my website with custom java script so my customers can change the radiobuttons, selects and the slider and a custom price is displayed.

Has anyone any idea how i can connect this calculated price with the add-to-card button, the card and the checkout.
My customers should be able to calculate their price for a specific service and than pay for it immediatly. Is this possible or do i have to make a product for each variant to connect it with the card?

Thank you in advance
