Clear Distinction between Invoice and Transaction payments

We have the option at our club for members to get monthly bills and pay via Invoice, or pay individual transactions, like a pay-as-you-go system, through Transactions. It would be nice if there could be a clear distinction between the two when looking up past payments. Since all payments show up under "Payments," it would be nice if those paid by Invoice would be marked as such to distinguish them from a Transaction payment. The only way to tell the difference currently is to go into the Invoices tab and check there if something shows up. Even having the Invoice # viewable in the Payments section next to the payment would help. If it has an Invoice number, you'd be able to quickly and easily tell it was an Invoice payment. Also, if you view a Paid Invoice, the date of pay does not show up on that Invoice. You have to go back to Transactions and check there. It just seems these things should have less steps to be able to quickly check things if questions arise and we on the admin side should be able to clearly see the difference between types of payments (Invoice or Transaction).
