Consolidates the billing of two subscriptions that belong to one customer. If AlignToCurrentInterval is set to true, the resource performs a pro-rated calculation of the cost of one subscription so that it can be merged with another subscription, and this results in a single billing event for a given period. You can also use the resource to calculate and preview the pro-rated cost of aligning two subscriptions.
