It’s often helpful to identify a SmartList Builder (SLB) SmartList to separate it from the defaults. That way if a change needs to be made you can readily identify the item as a SmartList Builder report to change or duplicate and change.
A simple way to do this is to include and identifier like [SLB] at the end of the SmartList Name. You could also put an identifier at the beginning if you want to group all SLB reports together.
