Today, your options are to use a third party solution, as Garry suggests, or learn how to use the
wbadmin command-line interface to the Windows Server 2008 R2 backup/restore engine. For the latter, please consult the help available from the server desktop, and Technet. Also, some time with a search engine may help you understand advanced use of
the built-in tools; how's your Google-fu?
As for the future, I don't know if Microsoft has any plans to change the way the wizard works. To be honest I'd guess not, though they've proved me wrong in guesses like that before. :)
I'm not on the WHS team, I just post a lot. :)
