Thanks for the suggestion, Alistair. We think a section for non-stock item purchases would be a great addition.
I can see that you haven’t voted for your own request, so that is worth doing, as this helps with our prioritisation (more info here). If anyone else would like to see this, please also give this thread a vote with the button in the top-left.
You should be able to do this already. If you’re on the “edit” screen, then you can click the View summary button in the top-right and then choose Actions → Print. This should let you save it to your computer to email too. I hope this helps
