Does anyone know how to copy an entity in Microsoft CRM 4.0. Right now I am going in 

settings>customization>new and creating a brand new entity with same attributes. I have to make multiple copies of this entity. Rather than manually doing it like I have been doing, is there an easier way of just making a copy of the entity and renaming it? 

I tried Export customizations and exporting the XML and remaning the all the entity1 to entity 2 and also changed the ObjectTypeCode. It didnt work when i imported. 

Any help is appreciated.
