Real-time "Unsaved" status, Intercepting Workflow Navigation

​I have a requirement to implement data integrity guardrails on several budgeting forms (Dashboards containing Cube Views/SQL Table Editor). I am looking for guidance on whether the following two features are technically feasible within OneStream:

​1. Real-Time "Unsaved Changes" Indicator

The goal is to display a status label at the top of the Dashboard that updates to "Data Hasn't Been Saved" the moment a user modifies a cell value (Cubeview/SQL Table Editor), before they actually click the Save button.

• ​Question: Is there a way to detect a "dirty" cell state or user input in real-time to update a dashboard component immediately, or are we limited to updating status only after a Save action is triggered?

​2. Navigation Warning (Popup on Exit)

The goal is to trigger a popup warning if a user attempts to navigate away from the current Workflow Unit or close the Dashboard tab without having Saved or Run Calculations.

• ​Question: Is there an event handler available that allows us to intercept a navigation event, and potentially block the user from leaving the screen until they complete the required actions?

​If anyone has implemented a similar solution or knows which Business Rule events controls these interactions, I would appreciate the insight. Thanks!
