I am working on building a custom registration process for a Community, and have things working with the CommunitiesSelfRegPage/Controller, but would like to build it out with a Community Builder Page. I see that I can customize the field labels and such of the Self Register Community Builder Page, but I would like to be able to edit the functionality of it, I do not see where I can edit that, as it is not showing up for me under pages or components. Am I missing something obvious?
