Hi Wollverine, I am experience SE and TC user. I can tell there is no such function. And to be honnest, it would be a quite complicated function. But I think it would be a great idea. Today in TC11+SE ST9 we have Mass Update. The works fine with replacing. I don't know yet if it works with adding. We don't have Multi structure editing, but as far as I understand this does also not support adding an item to multiple structures.
