You surerly need a gametracker account and i dont think there is a setting in tcadmin that logs in to gametracker database automatic and scan the servers.. So the answer is there is no such setting. It can be made by some scripting i think. I sugguest doing this Manually is better. You have more control then over everything. Every game server comes with pre made Banners you just need to log to gametracker and scan the server if i understod correctly?
