Is there a way to set mount options for thunar? It's not in thunar-volman-settings, if there is. Hope it's not "write a polkit rule" because there's no way the average user will be able to do that. 

I know this isn't a "bug", but don't see any other way to contact the development team. 

Right now, I'd give my eye teeth to be able to mount a usb filesystem without having all the filenames mapped to uppercase.
