Hi mir4ea, currently there is not any mechanism for making that "instancing" kind of clones. That is something I definitely want to add in the future, though. It will involve quite a lot of different pieces, with stuff for managing a list of current instances and mechanisms for creating new ones and editing the base object and having all the instances update, so it's like a combination of numerous features to get it all done, not just one single isolated feature really. So I'm not exactly sure when it will happen, maybe for v4.

It would definitely help conserve memory with heavier scenes that have some repeated complex parts.
