It sounds to me like what you're after is Overriding the JPA Annotations with an ORM.xml.

This will allow you to specify the Annotations but then override them only where they change. I've done the same to override the schema in the @Table annotation as it changes between my environments.

Using this approach you can also override the table name on individual entities.

[Updating this answer as it's not well documented and someone else may find it useful]

Here's my orm.xml file (note that I am only overriding the schema and leaving the other JPA & Hibernate annotations alone, however changing the table here is totally possible. Also note that I am annotating on the field not the Getter)
