Can't add shortcut arguments via File::createShortcut()

I’m using File::createShortcut() to … well, create a shortcut. It works just fine but I can’t figure out a way to add command arguments/parameters to the shortcut. Could that be something that is added to File::createShortcut()? I see File::startAsProcess() allows parameters to be specified, so I’d imagine this would be a straightforward addition.

Thanks!
