Glad to see it's already in there, so no dev time needs to go toward this.  It's so rare I actually need to select point to point subobjects for anything other than UV editing, that I wouldn't care if this were available or not.  I don't feel it's that big of a timesaver in my personal workflow, but I understand if you needed it, it's good to have it.  I've never had problems selecting subobject components in Max. The selection tools are so extensive, I feel most of them are probably unnecessary.  Take the Selection "Patterns", for example.  Does anyone actually have a use for those?
