Multiple packages in PKGBUILD and creating groups?

Hello, I have two questions, I merged it into one post to prevent people complaining about Polarian Notifications (aka me popping up on their email every 5 mins). Does anyone have a good reference I can use to properly make a multi-package PKGBUILD, I have no experience doing this and I want to stick to conventions, and the PKGBUILD ArchWiki page does not seem to cover it. Secondly, is it possible to create PKG groups within the AUR, I would like to group a few packages together, but I am unsure if I am allowed, or able to do this, unless it is added to an official repository.
