Email traffic reports do not included shared mailboxes

Email traffic reports do not included shared mailboxes

Exchange Report Plus 5.3 b5300 with Exchange 2013 CU20.

It appears that none of the email traffic reports included shared mailboxes. The only shared mailbox reports for on-prem Exchange are under Organization/Shared Mailbox Reports and those reports only provide a list of shared mailboxes and permissions for them, while Exchange Online reports do include more shared mailbox reporting, like traffic, size, etc.

Is there some way to get email traffic on shared mailboxes for on-prem exchange? I am looking to received/sent counts at the moment, but would ultimately like ALL mail traffic reports to be able to included shared mailboxes. I see no good reason to not include them, at least as an option.
