How to route Subscription Amendment Orders into the original Revenue Contract

"Hi team,

Currently, when we create an initial Sales Order for a Subscription, a new Revenue Contract is generated automatically.

However, when we later amend that subscription via a new Amendment Order, the system creates a second, completely separate Revenue Contract.

Is there a configuration, profile option, or standard grouping rule that allows both the original order and the amendment order to update the exact same Revenue Contract?
