This is actually a feature that is being worked on / ready to go for the development branch.

It'll take some time before it'll trickle down to the stable / prerelease branches but if you need it now you can find it on Github if you feel like compiling your own client and server. (Just be aware that the Development branch isn't always as stable or usable)
