Hello..We make extensive use of the recurring invoice function.  And we also like to see when a customer opens that recurring invoice to make sure it did not end up in spam, etc.  However, the history on recurring invoices is only limited to when it was sent.  There is no other history including when the customer opened that particular invoice. 

All other invoices show the history fine including when the customer viewed, etc. 

Is there some sort of setting we are missing for recurring invoices?
