Accessing Large Data Pivot Grid User Selections via Business Rule

Hi OS Community,

I'm exploring a potential enhancement and was wondering if anyone has experience accessing the user-configured state of a Large Data Pivot Grid through a Business Rule.

To clarify, I'm not referring to the component properties/configuration, which can be accessed programmatically. Instead, I'm interested in the information that a user defines within the Large Data Pivot Grid itself, for example:

• Whether the grid has unsaved changes (similar to a save status or "dirty" state)
• The fields currently assigned to Filters, Rows, and Columns (by user)

Since this information is configured within the UI, I'm trying to understand whether OneStream exposes the saved Large Data Pivot Grid layout (Filters, Rows, Columns, save state, etc.) to Business Rules, Dashboard Extenders, or any other supported API. My goal is to drive a custom Excel export and display warnings when unsaved changes exist. Has anyone implemented something similar or knows whether this metadata is accessible?

Thank you in advance for any insights!

Kind regards,

Andres
