Is there a way to set XML::Twig's preferences to pretty print using tabs instead of spaces?

I've made a perl script that modifies an XML file. But the resulting file now has spaces instead of tabs for indenting. I've looked around, and I can't seem to find a setting to switch it to tabs. I know I could do a search and replace on it, but that's an extra step for something that should be very common, so I was wondering if I missed something.
