You can scope on the procedure when the number of its expansion objects is small (it has no dialog flows in or out). Do not request Delete protection on the procedure because Delete also brings in all nested action blocks.
To maintain dialog flows, you must scope on the procedure.
However, scoping on the procedure step, Modify/Short, Design subset type, allows you to add the flows without bringing down all associated Procedure Action Diagrams (PrADs).
