How to import product to episerver commerce and leave it as draft(not publish)

Hi,

I am trying to write a custom import tool use CatalogImportExport  to import product to eppiserver and leave it as draft version, but i did not see any option to do it

Can anyone please give me the solution to this problem?

Here is my code

// Start import
using (var catalogXmlStream = new MemoryStream())
{
catalogXDoc.Save(catalogXmlStream);
// set stream pointer to beginning
catalogXmlStream.Seek(0, SeekOrigin.Begin);

// import back by episerver import export
CatalogImportExport cie = new CatalogImportExport();
cie.ImportExportProgressMessage += progressHandler.Invoke;
cie.Import(catalogXmlStream, true);
}

Thanks,

Thao Pham
