Is there anyway to globally change the user registration link?

I was able to change it in the individual K2 login module to point to the perma link for the menu/login component I am using (jcontact) but I was wondering if there is a place I could globally change it for the entire k2 system. I want to do as much as I can to funnel all registration through jcontact.

If there isn't one place I can change it for the whole system (would be a nice feature) what areas of the code do I need to look at (besides k2 login) for links to the registration system that I would need to change.

Thanks for the help and the awesome component!
