Is there a way hibernate provides selective reference loading in case of objects with multi-level references

Say my object references are as below,

ServiceModel > FeatureModel > AttributeModel > EnumModel

Bundle > ServiceModel (without any references)

I need to load the ServiceModel object graph in one instance ( with all its dependencies),
but during linking up of Bundle > ServiceModel, i dont need other references ( FeatureModel > AttributeModel > EnumModel) as this is unnecessary data according to the business scenario.

To solve this problem i created two model classes of ServiceModel

1. ServiceModelVO - Thick object with all references
2. ServiceModelThinVO - Thin object without any references

Bundle is related to ServiceModelThinVO, Bundle > ServiceModelThinVO

Is this the best approach to do so ? I followed the same approach for two, three other model classes as well resulting in lot of duplicate model bean classes. Does hibernate provide selective reference loading property ?
