How to assign different associated file name than dataset name

Hi All,

As I've created a C# journal to create CGM of my drawing sheet in NX and to be attached as a dataset in the item revision of team centre, I could do this. But could observed that the dataset name and associated file name are same actually my requirement is, I need to assign different associated file name than dataset name.

Can any one help me how to assign different name to the associated file
i.e if use cGMBuilder1.SetDatasetNames(xxx) it is creating same name "xxx" for dataset and "xxx.cgm" for associated file.

Thanks,
Venkat
