I'm in the process of converting my old Type1 MAC fonts to PC using CrossFont. Is there a tool/software that can change a families properties in batch? Particularly the Designer and Vendor ID property. Microsoft has "Font properties editor" software that does the job, only a single font at a time. It would most likely take me a year to complete the project that way.

You have this tool to convert fonts: http://www.fontlab.com/font-converter/transtype/
