Inserting blank posts for Data Lists at the beginning of a thread?

[Girls With Guns]

I believe I have seen this done before elsewhere on this forum, but I'm not sure - I setup a new thread in the Anime sub-forum "Japanese Anime Releases with English Subs/Dubs" which now has an expanding list of data in the first two posts at the beginning of the thread, and with my plans for the list, I'll soon be running out of room in the 2 posts due to the 30000 character limit per post. Is it possible to insert extra blank posts associated with the OP immediately after those full posts, so the OP can continue expanding the lists? When I originally created the thread earlier this week, I had no intention of putting any lists at the beginning of the thread, but so many people requested it to be added, I was forced to put the data in my existing first two posts (fortunately I posted two back to back), but I would now like to rearrange and expand the lists properly now. Is this at all possible?

If so, I would like to get 4 blank posts assigned to the OP Girls With Guns (me) added after the first two posts in the thread "Japanese Anime Releases with English Subs/Dubs".

If not, would it then be best to create a new thread and get the old thread locked or removed? Thanks very much for the help!
