We've added an ability to align the billing anchor of all paid subscriptions to the same anchor.

When selected and when customers have multiple active subscriptions either to the same product or to different products, the billing anchor of all of the paid subscriptions will be aligned to billing anchor as the first paid subscription. 

This allows invoices of multiple subscriptions to be generated on the same day. 

The configuration can be changed using no-code under the Account Settings section, and will affect all of the account's environments. Updating the configuration will affect all newly created subscriptions.
