IC2 Achievements - Adding an Achievement

Greetings fellow earthlings,

I have a quick question that pertains to the IC2 API and the IC2 achievements.

Is there a way I can add an achievement from my custom add-on mod to the IC2 achievement window?

Obviously, I know you can add them to the vanilla Minecraft achievements, I just don't see anything in the API that hints to the creation of an achievement under the IC2 page.

Thanks in advanced

I see how they do it in source, by registering a new page. Though the thing that is getting me is hooking into the IC2 page. I know I could probably register the page under the same name, but I am afraid I might accidentally override something.

So my question was does the API have an support for add-on achievements?
