It would be good if unselected invoices could be set to be updated as run for that month. There is a yes/no choice for this when processing recurring invoices, but it has never worked in all the time that I have been using Sage (and that is nearly 30 years) unless there is e setting I don't know about that stops the function working, of course....
still broken as far as i can tell - also would be great to have a select / deselect all button so you don't have to do them manually
