Add a 'page was updated' script when working on the PE console

We have a use case from a customer in which multiple admins are configuring nodes on the console at the same time, this leads to issues where node classifications are over written, causing in correct classification

The customer is requesting a feature in which multiple users can edit the console and not step on each other's toes per se, I think the best way to do this would be a notification which informs the admin who is making classifications within a node group that the page was just updated, so they know to refresh again before continuing making changes. Or that they continue and the differences between the saves are displayed
