Composite Primary Key in Persistence

Is there any way to have multiple ID's in one Entity? Corresponding JPA it should be possible. But trying in the designer I get: Exaclty one 'Id' field per Entity Class must be used. Although it is not named 'Id'. Would be saving a lot of work, when this is enabled.

Best Regards

To get the full feature set of JPA I copied the generated entity class from "src_dataClasses" to the "src" directory (with package directories) and deleted the entity class in Axon.ivy.

Now I can manage the entity classes in pure java. Also the "Generate Schema" button in the Persistence screen is working.
