Discount Purchased Individual Product Price From Bundle

I have a few bundles in my shop that include many individually sold products. I'd like to be able to use Cartflows' conditional logic to check whether a user has purchased a product that's included in the bundle in the past, that is associated with their account. If they have, I'd like to discount the value of the product they already purchased from the price of the bundle at the checkout, in which that individual product is already included.
