converting hibernate entities, using a pojo that will be composed of numerous entites of different types

I have ComplexCustomerResponse (not persisted), it is composed of data from various sources - CheeseEntity, EmployeeEntity, VehicleEntity. The entities are hibernate entities and shared across multiple projects.

To map/convert the data, I want to create a TemporaryHoldingObject that will look like :

temporaryHoldingObject.setCheeseEntity();
temporaryHoldingObject.setEmployeeEntity();
temporaryHoldingObject.setVehicleEntity();

And have nothing else in it, is there a correct design pattern/name for this object ?
