How to select multiple folder at once

Hi,

I cant make FileSelectFolder() to accept multilpe folder select on Choose Folder window when user press Ctrl and/or Shift.

Is there any parameter I should try?

I also try Melba's ChooseFileFolder(), but seems it also do not allow user to choose multiple folder by pressing Ctrl and/or Shift.

Thanks

PS: I know how to allow user to select multiple FILES, but i want to allow user to select multiple FOLDER, not files.
