Multi level Access Reviews

Hello All,

Does anyone have success creating multi level certifications in identityiq ? I mean an access review which initially goes to manager and then to application owner or entitlement owner. I would like to combine all the cert entities to a manager in a single certification(same for app owner). There are various compass posts abt leveraging pre-delegate or sign-off approver rules. But I did not quite understand how those rules will help to combine multiple certs for the same certifier.

if the pre-delegation or sign-off rule doesn’t help in combining/merging certs, has anyone succeeded in writing standalone rules for that ?
