Customized URLs

I do a lot of signings where I give the readers an option to just order and I can ship to them when I am home to save on shipping massive editions sometimes 3 times both to and from the event etc. I'd like to be able to customize the url when I cannot display the QR code so that it's easer for the reader and for me to track it. I.E. beventi.co/sales/HeatherLongTulsaSigning - etc.
