Sadly, no, not at this POD. The reason is that everyone, basically, uses the same shopping cart and there would be too many code that overlap and cause confusion.
What I did was keep creating codes over and over again - until I found a combination that was not "too" bad. In fact, I have two that are sort of cute and easy to remember. It just took dozens and dozens of tries to get there. For example - (for car buffs, maybe) I have one with VETTE as a root.
