When placing scope boxes they will come up with a default name Scope Box ??, where the question marks are a number.  If you rename a scope box to say Area 01 then use the scope box command to place a new one, it will come up with the name Scope Box ??.  However if you copy a scope box it will have a value one higher than the previous, so a copy of Area 1 will be Area 2, the same is true if the name was Area A it will be Area B.  So if there are going to be a multitude of scope boxes on the project think about renaming the first one and copying it around, easier to adjust shape than rename, or at least that is how I do it.
