Saving Multiple Objects as a Single Object

Hi, I'm trying to create a dice object, but I can't figure out how to save multiple objects into the gallery. I've used several circles and a cube to create a dice, but Alice only let's me save the individual objects. Is there any way to merge all the objects together, especially since I don't want individual parts moving, I jsut want it to act as a single object for everything it does.

Thanks!
