Conversion of thmx files to pptx file format

You can apply .thmx themes from older versions of Microsoft Office (2007) to Microsoft PowerPoint presentations (.pptx) and other Office documents created in version 2007. Such function does not seem to be available in latest version of MS Office unfortunately and it seems that it has been completely removed. This makes thmx to pptx conversion somewhat difficult to achieve without access to old version of MS Office.
