Is there any way to disable the auto-indent Xcode performs to align colons when breaking up a long method name into multiple lines?

That is, I'd rather not have this:

UIBarButtonItem *longDescriptiveButton = [[UIBarButtonItem alloc] initWithTitle:@"Title of Button"
                                                                          style:UIBarButtonItemStyleBordered
                                                                         target:self
                                                                         action:@selector(longDescriptiveButtonClicked)];

which, as you can see, looks terrible when variable/method/class names are long.
