How to put my campaign in selection screen?

I am working on this campaign and I am wondering how to make it selectable in the Campaign selection screen so you dont have use the Custom Game crap. Does anyone know how?

I believe you have to hack the war3.exe file in order to do it.

haha hacking it, you make it sound so bad and illegal. I think its more of hex editing it or modifying it, unless there is a simpler way.
