Using update(note) and paths together in a single note to limit cascading updates

Is there a way to use ‘paths’ [Which is a new information feature as in Get info: Paths] within a note’s rule so that I I can cascade -update(note)- to all its links downstream when a select attribute (or any attribute) of that note’s changes? If I can access (directly or through calculation) the last time the note was updated, then I can update selected downlinks notes without much overhead.
