Is it possible to save the file to external servers (Amazon S3)?

[ikril]

If you try to make an $excel->output() on s3://test/excel/excel.xlsx, we will get an error: [ERROR] workbook_close(): Error creating 's3://test/excel/excel.xlsx'. Error = No such file or directory

Is it possible to do this without saving the file to yourself, and then uploading it to s3?
