Selling Variable Pricing Option Change

Hi there,

Sorry if this has been asked. I’d like to know if there is a good way to sell an upgrade of a license type of a particular product. Each license type is sold with the variable pricing option like this

Product X
– Type A, $10 (id 0)
– Type B, $50 (id 1)
– Type C, $200 (id 2)

I’d like to sell an upgrade of the license types like this.

– A to B of Product X, $40
– B to C of Product X, $150

I mean after a customer purchases one of them, EDD internally updates the variable option of the previous purchase of the customer of Product X.

Is there already an option to do it?

Thank you.
