Include Expense Type on all invoice reports inside Tradeparency

A client has a need to be able to pull out a report that identifies what Invoices Not Submitted by Expense type for their finance team.  It is used for budgets etc.  Specifically needed for the invoice not submitted report for this case, but I think having that option would be useful on all invoice reports.  

That said, I know expense types are customizable which could cause problem, but if possible, it would be useful feature.
