What happens when you create additional storeys after cloning?
If cloning is set up to be done with additional parameters what will happen if you create storeys/sections/etc w/out proper ID? It will not be cloned. Then you add the ID and the item gets cloned. Automatically it'll rearrange layouts. Then you delete the ID and the layouts change again? Then multiply everything when you have x number of users with the same permissions working in TW...
The solution, IMO, would be to have subfolders in Project Map so that they can be cloned plus it will allow users to group items as needed.
