What do you mean?
You cannot predefine what people give you. It is up to them what they click, but you can put your preference into your city name and ask them nicely to polish the one you want. The common way of doing it is:
B for builder
C for culture
M (many use MH) for Main Hall
If you are the one helping then you can read your fellows/neighbours city name to check what they prefer, but it is always up to you what you want to click...
