I missed Prefab.
Correct me, but Grouping are not shown in CB. Only Blueprint & static components, & hence cannot use the migrate features. No biggy but it would be nice (as a time saver) to be able to do so.
At first I think, its no biggy, I just use blueprints (as replacement for Prefab), then I discovered that I cannot add a Blueprint assembly to another blueprint. (say I create door frame using a blue print, & a door assembly using blueprint, I cannot directly add them to blueprint to make a complete door structure).
If someone knows how to do it, let me know, that would be massively helpful.
