quicksetup materials fix + append multiple target parts from bulk select

don't send the edited material to SetMaterials (internal dynamic properties) if only one material exists (the submaterial dynamic properties become invisible in that case)

similar option to sending bulk select to proxy multi target, except it's appending, not overwriting existing ones, while preventing duplicate uids/names
