My Goal to export the worklist only with mainfile, how to achieve this?

• Currently “Export As Zip” in worklist export all files including file:content and files:files
• I tried to write an automation chain to implement this

- Context.FetchDocument
- Seam.FetchFromWorklist
- Document.GetChildren
- Document.GetBlob:
    xpath: "file:content"
- Blob.CreateZip:
- WebUI.DownloadFile

• But in the above chain, all files are placed inside single folder whereas in default export I can see folder for folderish document and its child files are placed inside the folder.
• How to achieve this? Want to create folder in the exported zip.
