Currently we can only have one approval workflow for all Separation of Duties (Sod) rules in Identity Applications. (Which we have to define as Default beforehand in the Configuration/Roles and Resources/Separation of Duties Settings). Since one can have multiple SoD definitions with potentially different semantics in the IAM System, it would be nice to have the possibilty to select from a set of (custom) approval Workflows for each SoD definition.
