There is a few ways to do this, in fact I just got a great idea of adding support to Texture Studio to export groups of objects to a FS that wouldn't require any kind of special editor you would just need to specify the center object all offsets can then be calculated by subtracting that objects X,Y,Z from all objects. The good news is that is such an easy extension for me to add, the bad news I'm not ready to release the next version of Texture Studio yet.
