Non chronological merging

[pokerie]

Hi there,
I've recently created a thread I want stickied and the first post of it is to be the intro to the thread. I want to merge older threads into the same thread and have them displayed "after" the intro. I want to merge a few threads into the one but I'm afraid with the chronological order of things, the posts could be all over the place. Is there any way just to add them non chronologically and more threadly (if that's a word)

Any feedback would be appreciated.
