I'm glad you asked that question! I was just working through how that might operate! Tell me more about what you'd like to see!
Here is my current thinking - I'll add some metadata to the extracted note about the sources of extraction so that if you select any notes with that metadata, they will refresh with the new or updated text. This could get a bit complex especially if the original source note changes significantly. (I'll look at automating that later with some type of refresh period).
Do you need the reverse - to update the original note if the extracted note changes?
