How to identify if a message is a repost in Viva Engage reports?

Hello,
I’m working with the exported reports from Viva Engage, and I’d like to know if there is any way — based on the messages data in the documentation or export — to determine whether a specific post is a repost of another one.

I have reviewed the schema documentation for messages, but I couldn’t find an obvious field that indicates if a message is a repost or links back to the original post. Is there a recommended field or approach to identify reposts programmatically from the exported data?

Any guidance or examples would be appreciated.

Thank you!
