Emails & Activities tracking emails on multiple items with the same email address

Emails & Activities tracks incoming and outgoing emails on all items that have the same email address in the email column.

Has anyone found a workaround to only have the emails show up on the item associated with the email thread, and not tracking the email on every other item that has the same email in the email column?

Unfortunately we have not - the Emails & Activities app tracks emails across all boards - even if the board is private. It would be great to see this fixed, but as far as I know it currently isn’t possible.
