Specifically Royal Mail for us! Ability to be selective in what you want to manifest that day in addition to the "Generate Manifest" which should read "Manifest All", it would be great to have the option to choose which ones you know are going that day so you don't have to cancel the current labels therefore confusing your customers! Would be great for a few integrations for end of day reports really, it's good to have the magic "all" button but there are many times I could do with excluding a few and currently the only way to do this is to cancel the label/s and deal with afterwards causing huge headaches!
