Hi Mike, yeah I want the grouping mechanism to enable a hierarchical structure so you could have parent and child groups.

I think that an instance mechanism will be another separate mechanism yet from groups, since it needs a fair amount of specific tools for it such as having a way to swap out the base definition and have all the instances update. Also an instancing mechanism is maybe more related to a type of library or catalog of stuff in some ways, while a "group" will probably be more of an structural organization tool... That's at least some of my current thinking anyway.

It would be nice though if object names, groups, and instances could maybe be more parts of one single system instead of 3 different types of things, but I'm not entirely sure yet if trying to combine them too much might make things more complex instead of better.
