Enterprise Contract (Sale Intent) Approval based on type of Amendment

We are looking for a requirement where we want to have a different set of approvals based on the type of amendment that's done on the Enterprise sales contract.

We mainly want to differentiate between Customer change amendments (which will be added as a third-party role) and other types of amendments.

Is there any way we can use a third-party role as an attribute or any DFF to differentiate on BPM approval rules for Contract approval?
