[New Feature Request] Attach all Files to a Row from an Existing Row from the Same Smartsheet

Hello. I use the C#.Net SDK and Smartsheet API to develop Smartsheet scripts for my company. I was wondering if the Smartsheet Development Team would add a way for Smartsheet API to attach all attachment files to a row from an existing row from the same Smartsheet. Currently, the smartsheet.SheetResources.RowResources.AttachmentResources.AttachFile() function only allows attaching a single attachment file from a local computer to a Smartsheet row.

Thank you for your response in advance.
