I'm happy user of my gotek with hxc firmware on my Amstrad cpc

I've just tried with my Thomson TO8, it works like a charm. However, if it seems I can write on disk with my gotek/hxc, i didn't find fd or sap format in the hxc software export option.
Is there a way to export a hfe file to fd or sap file?
I thank you for your answer
