portfolio rtf does not capture formatting and loses some text

I'd like to be able to create a portfolio from several pages and want to use the 'Word' or rtf format option, so as to create a single rtf file from several wiki pages. Ideally the rtf would capture the text and images reliably as well as maintaining the formatting as the pdf does, but that isn't happening. Am I using it correctly? Is it being reviewed for upgrade? Are there other export options?
