No because for EVERY subscription amount that you are going to charge, there needs needs to be a plan with that exact amount in your Stripe account. The subscription is different than the one time payment. With one time payment, you can dynamically add the variation amount and charge a total amount for one time. With subscription, there needs to be a plan (in your Stripe account) with the exact price that will be charged on a recurring basis. So at this moment, we don’t have an option that you asked for.
