Would be great to have a 'flag' to attach to Transactions in the Needs Action/Actuals page for when either myself or other parties who may look at invoices (including accountant as they may ask why something still sitting in there - especially at Year End).
When we discuss the invoices for payment, query something, won't pay that the queried one and then a couple weeks later the customer may ask why we haven't paid it....and I/we have forgotten already. I use to scribble on the printed invoice, but now, no paper.
Similar concept to in Excel where you can attach a 'note' to a cell.
