can this be done ? .....

Adding clones of objects that are categorized under "Objects" in FMB is piece of cake, MiWa posted instructions in first page. Skinning these objects is harder part but we can use splashscreen method to find out layout of the skin.

Another thing that could be possibly done is to merge two or more objects into new bigger one. Haven't try this but maybe it's possible.

PS
canonuk, have you added your Crane object, if not tell me what is it object number in FMB and I'll do it for you.
