[Starcraft II] Custom Units

[Rispetto]

Hey everyone,
As some may know there is a new tool with the Starcraft II editor that allows you to make your own custom units.
An example would be the "Uberlisk" from that one blizz con, where the Blizzard Designer showed everybody what the new SC2 Galaxy Editor can do.
Unfortunately I don't know how to do this. Obviously my editor is still in beta, so I don't know if they've even added this feature yet.
I've been searching but I can't seem to find anything. If anyone knows how to do this, please reply to this threat (with a small tutorial? )

Thanks,
Risp.
