If you want the posts to be viewed along with the comics even after the fact (from the archive), the only way to do that (that malkes any sense) is to use the comic post. It's been a while since I tried Webcomic, but it should have an area to include a blog post along with the comic.
If you want them viewed independently, you're stuck with them being, well, independent. But from what I read, that's not what you want.
