Feature Request: Ability to to edit the included units for Rolling Window charge in an Amendment

Status: currently being review by our Product Management

Reference Number: DE8310

Business Need: customer Z have customers who sign up for annual bundles. Because the bundles are annual they use the rolling window to keep track of their usage each month, so when they do go over their bundle amount they can charge them for overages. In some case when the customer goes 
over their bundle amount they purchase an additional add-on amount to the original bundle amount. So now they have a new usage amount to track for the remainder of the term. This is why they are requesting if we can have a feature to amend the subscription to update the rolling window amount.
