Update Symbol from Quartus Command Line

Not sure I follow why this is necessary. If you change a schematic, but it's ports are still the same, then the symbol doesn't have to be updated and schematic hierarchy above it has to be changed. The only time the schematic has to be changed is if the port list has changed(adding/removing ports), and whenever this occurs that almost always means I need to modify that schematic level anyway(why add a port and not hook it up.) I guess I'm saying is I've done schematic entry and never needed this to be automated, as there are always manual steps that need to be taken when it's done. Am I missing something?
