I have a managed package that defines an object whose Name is an Auto Number field. A customer who has the managed package wants to import some data from another org into his current org, and maintain the Auto Number values that he had in his original org, instead of having new Auto Number values assigned. 

I know you can ask Salesforce to allow you to use the Data Loader to write to the CreatedDate and LastModifiedDate fields. Will they also allow us to write to an Auto Number field?

(Before you suggest I temporarily change the field type to Text,l please note that the field is defined in a managed package, so I can't change its field type.)
