posts that I relate to are not auto-related to the first post

If I have a series of posts:

Post 1 Yesterday
Post 2 Today

When I create Post 2, I link it to Post 1. This seems to work fine, so when I see Post 2, I see Post 1 linked. But in Post 1 – I don’t see Post 2 linked.

I have series of posts that go up to 5 or 6 parts… and to edit each one to point to all the others is pretty laborious. I’d rather have post 2 point to post 1, 3 to 2 and 1, 4 to 3,2,1; 5 to 4->1, and 6 to 5->1 and that way they should all be linked to each other.
