Use case: The plan the users are on is one product with it's own pricing.

I want to create a new product with different prices and features that they can upgrade to and prorate the payment.

For example, I want to have these plans in Billing tab for my users or at least an option to give them links for upgrade from the one to the others:

97/m or 970/y

197/m or 1970/y

297/m or 2970/y
