Thanks for the suggestion, Brenda. I can see how this would be really useful.
I believe that the existing requests - Delivery manifest and mobile app to show ETA and outstanding casks/kegs to customer - encompasses what you’re looking for here. If you agree, can you please give that thread a vote (which will help to push it up the priority list) 
Thank you.
(If you don’t think that thread covers what you’re looking for and I’ve misunderstood, please let me know.)
