Add Benefit Groups with End Date via HSDL or Spreadsheet Loader

Hello Experts,

We're trying to achieve to add benefits groups in bulk with the End Date itself during the creation.

We tried to achieve the same from HSDL and Spreadsheet Loader which is given for Benefits Group under Evaluation and Reporting, but, irrespective of the either approaches we are not able to end date the Benefits Groups, it only adds the Benefits Group as of the start date.

We are currently trying to avoid the HDL route due to different security roles required, which might not be relevant for the Benefits Admins.

Any suggestion on how we can End-Date a Benefit Group during creation via HSDL or Spreadsheet Loader ?
