Is there any way to add your campaign to the Campaign screen?

So people play my campaign thru the "Campaign" button not the "Custom Campaign" button.
I got this idea because if my custom campaign features 3 or 4 races, people can just click respective button for a specific race without switching out to the file browsing menu, and it gets its own sub-buttons and 3D scene, like the official campaigns. Has anyone succeed doing this? Or is it impossible at all? Thanks in advance!

I reckon that'd take making a mod, instead of just a campaign.

Try to put all maps into one campaign and call them like:
Human Chapter One
Human Chapter Two
Human Chapter Three
Human Chapter Four
Human Chapter Five
Orc 01 Chapter One
... and so on
That's the only solution for this problem, because you cannot lock campaign so it would be awailable only after you finished the first. Good luck in your problem.

Thanx anyway. I guess the only way I can do it is to modify that UI\CampaignStrings_exp.txt
So that takes making a mod since I couldn't just import this file to my w3n and apply the change...
