How do I know which sub-account a message belongs to?
You can see which sub-account is assigned to messages in the Impact Dashboard from the messages table or the individual message settings.
Note: This feature is only available to Canvas customers.
In the Manage Messages tab, click the Fields drop-down menu . Click the Sub-account toggle  to display the sub-account field in the table.
The Sub-account field is displayed, showing the association between each message and its linked sub-account(s).
