This is a feature request. When working on typescript projects, I liked the 'fix all' code actions presented with other trivial code actions.

For example, consider this case:

These are trivial ones and these quick fixes can be applicable on save if I had configured

        "editor.codeActionsOnSave": {
            "source.fixAll": true
        }

But, would be nice if I could select a region and trigger fix of all errors in the selected region.
Or alternatively, like typescript or eslint extensions, present the fixAll (for the entire file) option using code action.
