There are lot's of ways to do this.

One way it's to compose your message with, for example, 'Letter +

A - 1st Place
B - 2nd Place
C - 3rd Place

And your keys will be something like 'A1212', 'B7823'....

Another way it's to use a different field for the location. That way you
will have a different key composing the two fields (Location+Key).
