Configure which stage strings to be confirmed when uplaoding files

When I upload multilingual spreadsheets as a PM, how do I configure which stage I would like the strings to be confirmed?

By default you have translation and proofreading, if you want you can configure advanced workflow and have 2nd proofreading for example and so on. You can enable the export option, like skip untranslated stings and so on, but with Excel files they would work because it’s a cell based format. Only export only translated or approved file would be working.
